Describe how 1st, 2nd, and 3rd class levers are different from one another. Indicate whether each class of lever is a speed lever, power lever, or whether it can be both. 3. WebMar 28, 2024 · Lactic acid fermentation is a type of anaerobic reaction that produces energy for bacteria. Your muscle cells also have lactic acid fermentation. During this process, the cells make ATP without any oxygen through glycolysis. The process turns pyruvate into lactic acid and makes NAD+ and ATP.

WebOxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. WebA) ATP energy is used to move the myosin head from a low energy position to a high energy, ready position, then released with myosin and actin interact. B) ATP energy … WebATP supplies the energy for muscle contraction to take place. In addition to its direct role in the cross-bridge cycle, ATP also provides the energy for the active-transport Ca ++ pumps in the SR.
