Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The energy in fuel is converted into ATP, most ATP is made within the mitochondria. ATP powers the cells within muscles. • What is the role of glycolysis? Include the reactants and the products.
Here the three carbon pyruvic acid molecule is processed to produce ATP and carbon Dioxide molecules. This cycle uses ATP to specifically break down the pyruvate into Acetyl co-A. Once this goes through the cycle limited ATP as well as more NADH is produced .This happens in the mitochondria when sufficient oxygen is present to turn the carbon Dioxide. Is the role of the electron transport system? Include the reactants and the products.
Diagrams of Lock and Key Model A3b. Diagram of Activation Energy A4. Substrate The substrate of Aldolase B is fructose-1-phosphate. This comes from the breakdown of fructose by the use of fructokinase. Aldolase B is then converted into 2 products, DHAP and glyceraldehyde.
Electrons can now continue to move through PSII and the cytochrome b6 f complex, and oxygen is produced in the water-splitting reaction. 34. Bioenergetics of Photophosphorylation The steady-state concentrations of ATP, ADP, and Pi in isolated spinach chloroplasts under full illumination at pH 7.0 are 120.0, 6.0, and 700.0 mM, respectively. (a) What is the free-energy requirement for the synthesis of 1 mol of ATP under these conditions? (b) The energy for ATP synthesis is furnished by light-induced electron transfer in the chloroplasts.
Two ATP molecules are gained in this stage. The transition stage takes place in the mitochondria. The pyruvate is combined with NAD+ to form NADH and acetyl coenzyme A molecules. In citric acid cycle stage the hydrogen atoms are removed from the acetyl coenzyme A molecules to use the electrons to create ATP. Eventually, all that is left of the acetyl coenzyme A molecules is carbon, which combines with the oxygen to from carbon dioxide that is emitted as a waste product.
Adenosine triphosphate is the energy storage molecule made using energy released during respiration and subsequently broken down into adenosine diphosphate and phosphate so that its stored energy is released to allow activities in cells to be performed. The reaction is summarized as follows: adenosine diphosphate+phosphate+energy⇌adenosine triphosphate | Both aerobic respiration and anaerobic respiration begin with glycolysis in the cytoplasm. During glycolysis the substrate glucose is split into two pyruvate molecules. Enough energy is released to make 4 ATP molecules, but 2 ATP molecules are used so that the net gain is 2 ATP molecules per glucose molecule. Then if oxygen is available both animal and plant cells carry out aerobic respiration in the mitochondria of the cells.
Toshiba | The stages of cellular respiration and photosynthesis. | Biology 1 | Jasmin Perez 6/5/2013 | Cellular respiration has three stages. The first stage is called Glycolysis, from there, the second stage is called Citric Acid cycle, and the final stage is the Electron transport chain. All three of these processes help the cell to create ATP which is what our body needs for energy. Cellular respiration does a lot more than just creating energy for us, it also helps us breathe and control our sugars.
The chemical produced by the digestive system that breakdown foods are called enzymes. One of the main substances required for energy and resulting from the digestion is glucose. This is stored as glycogen by the liver and is released back into the circulation as glucose when required. The pancreas produces insulin which plays a role regulating blood glucose levels. Glucose is important because it is an energy molecule that is broken down to give the cell ATP energy to use for the cell’s
