The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP. ATP os a large source of energy for muscle contractions and can therefore be referred to as "energy currency" of the cells. The fuel molecules is first converted into acetyl-CoA and then can be inserted in the Krebs Cycle. Looking at the path of a nutrient, such as glucose, the oxidation of the molecule takes place in the glycolysis.
ASSIGNMENT 02 DUE DATE: 15 SEPTEMBER 2017 UNIQUE NUMBER: 76029608 STUDENT NUMBER: 62449842 Question 1 The general pathways for ATP generation include aerobic respiration, anaerobic respiration and fermentation. Aerobic respiration can be referred to as the breakdown of glucose molecules in the presence of oxygen and water to release energy in the form of ATP. The other products of this reaction include carbon dioxide and water.
This step results in the formation of Glyceraldeyde 3-Phosphate. All the following steps occur twice, once for each molecule of Glyceraldeyde 3-Phosphate. These next steps are the energy generation steps. Step six starts off by the enzyme Glyceraldehyde 3-Phosphate Dehydrogenase.
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
Chloroplasts are organelles that carry on photosynthesis; carbon dioxide diffuses into the chloroplasts in the leaves (Mader, S. 2010). Sugar and oxygen are released during the process. In order to photosynthesize, plants depend on light energy from the sun. The rate of photosynthesis will increase or decrease depending on the colour of light being absorbed, blue light results in the most photosynthesis occur and green light results in no photosynthesis occurring.
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy.
The light energy comes from sunlight and is used to convert carbon dioxide and water into other chemicals needed for growth (BBC). Plants perform photosynthesis to generate food and energy they need for growth and cellular respiration. They require light energy from the sun, water, and carbon dioxide. Water is absorbed from the roots in the soil to the steam and reaches the leaves. Carbon dioxide is from the atmosphere and goes through the pores of the leaves called the "stomata".
Breathing is the transportation of oxygen across from the air in the lungs to circulating red blood cells (erythrocytes) which pass on the oxygen onto cells which require and utilise the oxygen, during aerobic respiration, to produce energy in the form of ATP. This biochemical reaction produces carbon dioxide as a waste product, and it is transported, using the red blood cells (RBCs), back to the lungs and exhaled. Figure 1 shows the relationship between breathing and cellular respiration, with the two connected by the gas carrying red blood cells. Notice the requirement for oxygen by the cells to produce energy in the equation at the top – breathing is how this requirement is fulfilled, whilst venting the waste products from respiration
A fatty acid contains a long hydrocarbon chain and a carboxylate group. Fatty acid synthesis is a process which only takes place in the cytoplasm of the cell and it consists in producing fatty acids from acetyl-CoA and NADPH. This process requires great amounts of acetyl-CoA, and most of it that is used is formed in mitochondria. The intra-mitochondrial acetyl-CoA initially reacts to form citrate, as the inner mitochondria membrane is impermeable to this compound. Tricarboxylate transport system is used to pump out the citrate out from the inner membrane which will then be cleaved in the cytosol by citrate lyase, in order to regenerate acetyl-CoA. When acetyl groups are transferred to the cytosol, oxaloacetate is formed and needs to be
8. What is the role of cellulose? a. The main role of cellulose is to be a structural molecule and support for cells. Cell walls are made from cellulose, which results in the tough inflexible support wall. 9.
