In reference to muscle metabolism, how does ATP synthesis occur, what are the immediate needs for energy for a muscle both short term and long term, what causes fatigue of a muscle and describe maximum oxygen uptake in endurance?
Homework Answers
ATP production occurs by glycolysis, creatine kinase and
cellular respiration in mitochondria
Needs for ATP for muscles for short term is to produce intense
energy and for long term as a storage source. This helps in better
regulation and functioning.
Muscle get fatigue due to deposition of lactic acid as a result of
anaerobic respiration.
The maximum rate of oxygen consumption during endurance is referred
to as VO2 max

EXERCISE 4: Muscle pH 28. If you recall, there are three different metabolic pathways driving ATP production in skeletal muscle that are active at all times. However, the predominant pathway at any given time depends on the speed of the pathway and energy demand of the muscle. a. Which metabolic pathway predominates once creatine phosphate is depleted and before oxidative phosphorylation can occur ? Where does this occur within the cell? b. What is pyruvate converted to when oxygen delivery...

Humans produce energy in the form of ATP in their cells. They must have both oxygen and glucose for aerobic cellular respiration. Questions: - Describe all of the organ systems that would be necessary for this process to be successful. - Insulin is a hormone that signals muscle and liver cells to open channels to allow glucose to enter into the cell for storage and use. Identify the organ system that would be responsible for producing insulin and the type...

What is fermentation? Under what conditions does it occur? What is its purpose? Describe the major differences between anaerobic and aerobic respiration in terms of reactions, products, and energy yield. Yeast is capable of both aerobic and anaerobic respiration, but frequently performs anaerobic respiration regardless of the oxygen content of its environment. What advantage might this provide the yeast?
