Anatomy and physiology Assignment 1 of 3 Cell ultrastructure Light and Electron microscope uses light and electron microscopes are both used to see objects which cannot be seen with the naked eye, however the electron microscope has far more magnification levels; 0.2nm magnification 250,000 times, these allow you to see the ultrastructure of cell (Reid, 2017). A light microscope is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows (Alberts, B), Light microscopes magnify up to x1000 eye piece x10 objective x10, x40, x100, With these we can see the gross structure of cells, can be used to see small living organisms. Any objects smaller …show more content…

Animal cell organelles and their roles (powerpoint image) 1- Nucleolus- part of the nucleus which makes ribosomes. Produces ribosomal subunits from proteins and RNA also known as rRNA, they are then cent to the rest of the cell where they combine into complete ribosomes. 2- Nucleus – contains chromatin that contains DNA, which controls the activity of the cell, the nucleus is enclosed by a nuclear envelope Where DNA is stored, replicated and copied into RNA. 3- Ribosomes – bound to the rough endoplasmic reticulum, built from RNA and proteins that make new proteins, they consist of two subunits one smaller than the other. Ribosomes are made of equal parts of proteins and RNA. 4- Vesicle - composed of a lipid bilayer, used to move materials from one place to another, it too plays a role in metabolism and storage. 5- Rough endoplasmic reticulum – this manufactures and packages proteins. This is covered with bread like structures called ribosomes. 6- Golgi apparatus – modifies proteins and sends them to other parts of the cell. Consists of flattened membrane sacks called …show more content…

The mitochondria in the cells convert ADP into a useable form of energy: ATP. Cells gain energy by breaking down glucose during respiration, Glucose is broken down in many stages, tiny amounts of energy are produced and moved to ATP, the first stage of respiration is glycolysis, which takes place in the cytoplasm where glucose is split in pyruvate which needs the input of two ATP molecules (Reid 2017), in glycolysis the pyruvic acid molecules are reformed, three carbon pyruvic acid molecules convert to acetyl-CoA. The pyruvic acid molecule is broken down by an enzyme, and a carbon atom is freed producing carbon dioxide, and the two left over carbon atoms are combined with coenzyme A. This mixture makes acetyl-CoA. In the process, electrons and a hydrogen ion are transferred to NAD to form high-energy NADH. Following glycolysis, comes the Krebs cycle, also called the citric acid cycle which uses the two molecules of pyruvic acid made in glycolysis and yields high-energy molecules of NADH, FADH2 and some ATP. By the end of the Krebs cycle, the final product is oxaloacetic acid, and receives an additional acetyl-CoA molecule to begin another turn of the cycle. The Krebs cycle forms two ATP molecules, ten NADH molecules, and two FADH2 molecules. The

Summary Of Organelles As Organism

288 Words | 2 Pages

Organelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.

Did you know that there are over 82 schools in virginia beach? In many ways, an animal cell can be compared to a school. The Organelles’ roles in the cell align with the functions of a school in many different ways. Some examples are the Cytoplasm, Cell Membrane, and the Nucleus. One object in a cell that can be compared to a school is the Cell Membrane.

This small component controls the level of materials such as water in the cell. It-the mitochondria-also recycles and decomposes fats, carbohydrates, and proteins, but most importantly, it produces proteins for the cell through chemical reactions. Vacuoles are membrane-bound sacs for storage, digestion, and waste removal that also help plants keep their shape. In a computer, the Random Access Memory and Spam programs resemble this organelle because of the fact that RAM saves and sends information to memory chips. On the other hand, Spam stores unwanted material such as junk e-mail(s) and gives you the privilege of reopening this mail at any time.

White Houses: The Gates Of The White House

A cell is like the white house,It has many areas that work differently and have their own job’s to do just like a cell itself . The gates of the white house can be known as the cell wall because the gates surround the white house protecting it from bad things or people who shouldn’t go into the area or premassis. There are people who make things such as clothing or tools inside the white house so this area can act as the smooth endoplasmic reticulum,as for the rough endoplasmic reticulum,the doors can be referred to this because the doors only let certain people into the white house such as the president and his family,the security guard’s because they need to protect the area from bad people and the senators to discuss their work.

Fundamental Organelles In Eukaryotic Cells

1500 Words | 6 Pages

Figure 1: Type of cells The fundamental organelles in eukaryotic cell include: mitochondrion that is the powerhouse of metabolism, generating energy by process of respiration in the form of Adenosine Triphosphate (ATP) .It has its own stranded DNA hence able to self-replicate itself and multiply to replace the worn out cells during process of respiration .The mitochondrion is sac-like in its structure. The cell membrane is an organelle with the ability to select permeable substances into the cell hence able to transport desired material into the cell. In prokaryotic cells, the cell membrane is made up of glycolipid and glycoprotein thus providing mechanical resistance to the cell by being the base of attachment for cytoskeleton in some organisms.

Essay On Mitochondria

1361 Words | 6 Pages

The word mitochondrion describes its size and shape and comes from the New Greek for “mitos”, which is the word for “thread" and “chondrion”, which is the word for "small grain". They are normally between 0.75μ and 3μm in diameter but they vary considerably in structure and size. Mitochondria are made up of compartments such as the intermembrane space, the inner membrane, the outer membrane , the cristae and matrix. The number of mitochondria that are present in different organisms, tissues, and cells varies greatly. For example, red blood cells have no mitochondria and liver cells contain over 2000.

The cytoskeleton also allows organelles to move around within the cell by providing tracks with its protein filaments. This is important as it ensures the correct concentration of the required components is kept at the different sites within the cells. The 3 classes of filaments that make up the cytoskeleton are polymers made up of protein sub-units. The microtubules are the largest and provide the cell with its dynamic shape. It is these fibres that undergo continual assembly and disassembly.
