What process produces molecules of ATP and has two pyruvic acid molecules as end products?
Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of pyruvic acid (3 carbons each). This produces 2 ATP and 2 NADH. Glycolysis takes place in the cytoplasm.
Which of the following are commonly used to produce ATP during muscle contraction?
Creatine phosphate is formed from creatine and is used in skeletal muscle and the nervous system with ADP to produce ATP and creatinine, which is the final nitrogenous waste product [163].
How does a resting muscle generate ATP?
In a resting muscle, excess ATP transfers its energy to creatine, producing ADP and creatine phosphate. This acts as an energy reserve that can be used to quickly create more ATP. When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine.
What event directly triggers the release of neurotransmitter shown in A?
What event directly triggers the release of neurotransmitter shown in A? > diffusion of Ca2+ into the axon terminal. An enzyme known as acetylcholinesterase is present in the synaptic cleft.
What are the three ways that ATP can be produced in muscle fibers?
ATP is replenished within muscle fibres in three ways:
- from creatine phosphate (anaerobic)
- by glycolysis (anaerobic), and.
- by cellular respiration (aerobic respiration), whose initial stage is as for glycolysis, then continues via another pathway that includes oxygen and generates much more ATP.
How many ATP molecules are produced in anaerobic glycolysis?
2 ATP molecules
The anaerobic glycolysis (lactic acid) system is dominant from about 10–30 seconds during a maximal effort. It replenishes very quickly over this period and produces 2 ATP molecules per glucose molecule, or about 5% of glucose’s energy potential (38 ATP molecules).
How many ATP are produced in anaerobic respiration?
2 ATP
Thus, the ATP molecules produced in anaerobic respiration is 2 ATP.
How Lactic acid is produced in muscles?
Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.
Is pyruvate produced in anaerobic respiration?
Glycolysis breaks down glucose (6-C) into two molecules of pyruvate (3C), and also produces: A small yield of ATP (net gain of 2 molecules) …
What event directly triggers the release of neurotransmitter shown in a quizlet?
What event directly triggers the release of neurotransmitter shown in A? A nerve impulse arrives at the axon terminal triggering the opening of Ca2+ channels, which allows for the diffusion of Ca2+ into the terminal. This in turn leads directly to the release of neurotransmitters by exocytosis.
Which of the following ions directly triggers the release of neurotransmitters into the synaptic cleft?
This influx of calcium ions triggers a series of events, which ultimately results in the release of the neurotransmitter from a storage vesicle into the synaptic cleft. The first step in this process involves freeing the neurotransmitter-containing vesicles from the bonds that hold them to the cytoskeleton.
