7. Peroxisomes-Peroxisomes are responsible for the transfer of hydrogen coming from substrates to oxygen. 8. Bound Ribosomes- bound to some endoplasmic reticulum, these structures are responsible for the synthesis of proteins and polypeptides. The proteins that have been synthesized then become part of the membrane or exported out of the cell.
Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.”
A. Were the seeds in the “N” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer. The seeds in test tube "N" underwent respiration. Respiration is always happening.
2. Explain the functions of the respiratory system. Cite the definitions and the differences between external and internal respiration. The respiratory system is responsible for bow we intake air into our bodies and out.
The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.
Heart, lungs and the Rest of You By: Olivia Abel 1.Explain how the blood flows throughout your lungs, heart and the rest of your body. Heart: Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body.
An experiment was conducted in order to determine the oxygen consumption in dry and soaked peas within two different temperatures of water. Cellular respiration is the release of energy by metabolic chemical oxidation in the mitochondria, (DeStefano 2016). The hypothesis was the germinating warm water peas would have the highest rate of oxygen consumption. Within this experiment, a twenty-one degree celsius bath and a six degree celsius bath were set up. Then, a one hundred mL graduated cylinder was filled with fifty mL of water.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
the runner wasn’t using as much energy and carbon dioxide so it took longer for the solution to turn yellow. After exercising, the runner gained more energy as the cellular respiration process accelerated in their body. The increased amount of exercise led to the runner sweating, panting and breathing heavily to maintain homeostasis. Also, you breath much more briskly (increase in heart rate) in order to increase the oxygen intake and ensure that the cells inside the body are adequately supplied with oxygen. Once you stop exercising and the cells return to normal energy needs, less carbon dioxide is created, allowing your breathing rate to return to normal.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Cellular respiration There are three stages in cellular respiration: Glycolysis, the Krebs cycle and the electron transport chain. The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
The foods that you eat can affect the efficiency of cellular respiration. Cellular respiration needs the nutrients that you supply your body with through eating to occur. The first step of cellular respiration is glycolysis, then the Krebs cycle, and then the electron transport train, all of which require glucose in order to occur. So if a person eats a lot of sugar, then they will have a lot of glucose for the body to utilize and cellular respiration will be very efficient. However, if somebody is eating less sugars due to a diet or medical problem, then there will be less glucose for your body to use for cellular respiration and therefore, the three steps of cellular respiration will not be able to occur as much because of the lack of glucose,
Role of Enzymes in Metabolic Pathways Summary Metabolic pathways are a sequences of steps found in biochemical reactions in which the product of one reaction is the substrate for the next reaction [3]. Metabolic pathways most likely happen in specific locations in the cell. The control of any metabolic process depends on control of the enzymes responsible for the reactions occur in the pathways. After food is added to the body, molecules in the digestive system called enzymes break proteins down into fats into fatty acids, amino acids, and carbohydrates into simple sugars (for example, glucose). Enzymes plays an important role in the different metabolic pathways [5].
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
