Another molecule of NADH is produced in the process. Because energy must be conserved, organisms constantly recycle energy and thus need no input of energy. The body can use sugar, amino acids, and fatty acids as energy sources when needed. In this situation, the second law of thermodynamics must not apply. That's where calories come in. Cellular Respiration Stage I: Glycolysis. After passing through the electron-transport chain, the "spent" electrons combine with oxygen to form water. Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of an ion into the cell AGAINST the ion's concentration gradient? Living organisms must increase the entropy of their surroundings. Which of the following statements about cellular metabolism is false regarding. The graph will be a line with a positive slope. Describe the process of the citric acid cycle (Krebs cycle) and identify its reactants and products. In general, the hydrolysis of ATP drives cellular work by __________. The graph will be a bell shaped curve.
Explain why the process of cellular respiration described in this section is considered aerobic. The transition reaction is a very short reaction which converts the two molecules of pyruvate to two molecules of acetyl CoA, carbon dioxide, and two high energy electron pairs convert NAD to NADH. Learning Objectives. Phosphorylation of eIF2. The end products of the electron transport chain are water and ATP. It's then harvested in forms that can power the work of the cell (for instance, through the synthesis of ATP). Is there any cell that doesn't use ATP as its "energy currency"? The chemical synthesis of ATP. Heterotrophs (like humans) ingest other living things to obtain glucose. The energy contained in the electrons of these atoms is insufficient to reduce NAD+ but adequate to reduce FAD. Which of the following statements is not true for metabolism in living organisms. Phosphorylation of transcription factors. Course Hero member to access this document. The space occurring between two or more membranes.
Created by: CK-12/Adapted by Christine Miller. Cells have the ability to store heat; this cannot happen in a test tube. Can we artificially create another energy currency molecule? ATP is adenosine triphosphate.
T. Δ. S. tells you if a process is spontaneous? In this stage, energy being transported by NADH and FADH2 is transferred to ATP. There, pyruvate will be transformed into an acetyl group that will be picked up and activated by a carrier compound called coenzyme A (CoA). B) Liver and muscle cells are the primary storage locations for glycogen in humans.
