MED 208 – ASSIGNMENT 1 Avantika Narasimhan 2013M007 1. Define ion channels. Ion channels are proteins present on the cell membrane. They are pore forming and they facilitate the movement of selective or non-selective ions across the cell membrane. 2. Classify ion channels. TYPE DESCRIPTION Voltage gated ion channels They can be opened or closed according to the changes in the membrane potential. Ex: Activation gate of Na+ channel is opened during the upstroke of action potential in depolarization

Introduction The plasma membrane is an outer layer that is formed around the cell. It is composed of phospholipids and proteins and this is structure is crucial to all cells in our bodies. The plasma membrane acts as a border and more importantly is responsible for what is allowed to enter and leave the cell. The ability to allow specific molecules to enter and leave the cell is known as selective permeability and it is the phospholipids that make this unique ability possible. Membrane has a bilayer

There are some integral proteins embedded in the phospholipid bilayer. Carrier protein is one of the integral proteins. The carrier protein provides the passage for the ions or large, polar molecules to move across the cell membrane. Some of the ions or molecules need to make use of the carrier proteins with the help of concentration gradients. Nonetheless, some molecules which are important to human body sometimes need to go against the concentration gradient. There are two types of ways

While no longer young, I was over forty without a serious career. With an interest in ballroom dancing, I worked as a volunteer disc jockey for my uncle’s dance club. This gave me a new set of acquaintances to interact. This was also a place to network. I was willing to work any job, even a low-level one or a side job to pay bills. Without knowing it, this worked to my disadvantage. One hiring manager looking at my employment history told me that I was too willing to work any job. She said she would

turn on 1 foot, turn with leg horizontal, etc.. There are many different jumps that are done on beam that include: straight/tuck/pike/wolf/straddle jumps, sissones, and etc.. Leaps that gymnasts will do include: cat leaps, split leaps, switch leaps, etc.. Lastly the skills that have gymnasts get off the beam are dismounts these will include: round offs, front tucks, back tucks, backhandspring connections, and etc..

Peroxisome Peroxisomes are small vesicles found in the cell which contain digestive enzymes which break down toxic materials found in the cell. These enzymes are oxidative enzymes, such as catalase and urate oxidase. Peroxisomes play a role in digesting fatty acids, alcohol and amino acids, and also synthesises cholesterol. Hydrogen peroxide (H2O2) is produced as a by-product of these integral reactions, which is toxic to the cell. Because of this, the peroxisome breaks down this product down

an example of the molecules that are synthesized are lipids (Simon, Dickey, Hogan, & Reece, 2010). The Golgi apparatus are stacked membranes along with vesicles. Vesicles are small membrane surrounded bags that transfer materials from the rough ER (endoplasmic reticulum) to the Golgi apparatus. This means that the vesicles are shipping, storing and modifying materials in the Golgi apparatus from the rough ER (endoplasmic reticulum) (Project, 2004). The respiration in a eukaryotic cell happens in

A) Explain in detail the subcellular organelles are functioning effectively? Cells are basic structural and functional unit of living organisms. They are either multicellular or unicellular. Arise from pre-existing cells. Cell function as tiny specific factor with individual part that work together. Then what makes is present inside the cell that makes the cell alive and in turn, keeping the organism going? It is definitely the organelles! What are organelles? Organelles are membrane-bound, specialized

Golgi Apparatus- The golgi apparatus modifies the products of the endoplasmic reticulum. It also creates some macromolecules like pectin and and other non-cellulose polysaccharides. The Golgi apparatus sorts the different materials into the transport vesicles with the help of molecular identification tags. 6. Lysosomes- Lysosomes are coined as the “suicide

GOLGI BODY - In Golgi Body each flattened sac is smaller than the previous one, there are many vesicle cluster around the Golgi body, the vesicle that cluster around the Golgi body brings materials to and from the Golgi apparatus. Golgi body serves as a processing compartment of proteins and packaging it into vesicles. ENDOPLASMIC RETICULUM - This is ribbon like

Ribosomes The ribosome is like SpongeBob because he makes krabby patties for the Krusty Crab, just like the ribosomes makes proteins for the cell. Chromatin Chromatin is like Google because Google has information we need to look stuff up. While the chromatin stores information about DNA and holds the information the nucleus needs. Lysosome The lysosome is like a mushroom, the mushroom breaks down dead plants, animals, and waste. While lysosomes digest dead organelles and

In every cell there are three main parts: the nucleus, the cytoplasm, and the cell membrane. The nucleus is a spherical body usually located near the center of the cell that contains the genetic code of the cell and its purpose is to serve as the control center. Cytoplasm is the fluid medium for the many molecules and organelles the cell has. The cell membrane is the outer layer that separates the cell from its environment and controls what enters and leaves the cell. The nucleus is the control center

carbohydrates and nucleic acids. The cytoplasm is also largely made up of water which is an inorganic compound. There are many different organelles found inside the cytoplasm. These include the mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus, lysosome, peroxisomes, and vacuoles/vesicles. The mitochondria, known as the powerhouse of the cell, are bounded by a double membrane wherein each membrane is made up of a phospholipid

eukaryotic cell are the nucleus, mitochondria, ribosomes, and the Golgi apparatus (Daempfle, 2016). Since we have identified all the organelles within the eukaryotic cell, I will highlight which organelle I believe is the most critical to the cell.

One thing that all cells share is that they all have a Plasma Membrane. The plasma membrane is composed of proteins, carbohydrates, cholesterol and phospholipids. It is located beneath the Cell wall and is much more flexible when compared. The plasma membranes functions are to protect the contents of the cell and control the migration of particles moving throughout the cell. The nucleus is the most important organelle for a eukaryotic cell as it controls the cells growth and reproduction. The nucleus

Prokaryotic cells are different than eukaryotic cells in many ways. Prokaryotic cell means before the nucleus and eukaryotic cell means possessing a true nucleus, emphasizing that a prokaryotic cell doesn’t have a nucleus and a eukaryotic cell do. Other differences are the types of organelles. Prokaryotic cells have free floating D.N.A. and eukaryotic cells have it enclosed in the nucleus. Also prokaryotic cells have the ribosomes by themselves while eukaryotic cells usually are ether free or attached

structure. I learned that both are very similar, however, Plant cells do have an extra structure that makes them to be different than Animal Cells. An Animal cell is divided by a Mitochondria, Ribosomes, Nucleus, Endoplasmic Reticulum, Cell Mebrane, Golgi Apparatus, Cytoskeleton, Lysosome and Cortisol. Their functions are as follows:

Cell membrane- the blue outside layer on my model: The cell membrane is made up of a phospholipid bilayer. The membrane excludes, takes in, and excretes various substances, all in specific amounts. In addition, they must able to communicate with other cells. The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication. Nucleus- the swirled light blue ball in

Plants In a eukaryotic cell, there are many organelles present. These are a nucleus, golgi apparatus, mitochondria, lysosomes and a cell membrane. The nucleus stores DNA and controls the activity of the cell. The Golgi apparatus is present in a eukaryotic cell because it packages proteins and distributes them. The mitochondria provide energy to the eukaryotic cells. Lysosomes contain enzymes that can help the cell through the process of digestion. All the organelles present in a cell work together

A prokaryotic cell is a bacteria cell, the beginning ‘’pro’’ means ‘’before a nucleus.’’ Eukaryotic cells are either plant or animal cells, and the beginning ‘’eu’’ means ‘’possessing a true nucleus.’’ This means prokaryotic cells have no nucleus while eukaryotic cells do have a nucleus. Another difference between prokaryotic and eukaryotic cells is that prokaryotic cells always have a cell wall while only plant eukaryotic cells have cell walls. The larger, more complex cells are eukaryotic cells
