Question: What are the priorities during Fed state (after a meal)?
Answer: The priorities during Fed state (after a meal) are to supply sufficient glucose to the brain and RBCs and to preserve protein.Question: What processes occur during Fed state (after a meal)?
Answer: During Fed state (after a meal), Glycolysis and aerobic respiration occur. Insulin stimulates the storage of lipids, proteins, and glycogen.Question: What processes occur during Fasting (between meals)?
Answer: During Fasting (between meals), hepatic glycogenolysis is the major process, while hepatic gluconeogenesis and the adipose release of FFA are minor. Glucagon and epinephrine stimulate the use of fuel reserves. Question: What is the role of insulin during Fed state (after a meal)?
Answer: During Fed state (after a meal), insulin stimulates the storage of lipids, proteins, and glycogen.Question: What hormones stimulate the use of fuel reserves during Fasting (between meals)?
Answer: During Fasting (between meals), glucagon and epinephrine stimulate the use of fuel reserves.Question: What is the major process during Fasting (between meals)?
Answer: During Fasting (between meals), the major process is hepatic glycogenolysis.Question: What is the role of glucagon during Fasting (between meals)?
Answer: During Fasting (between meals), glucagon stimulates the use of fuel reserves.Question: What is the role of epinephrine during Fasting (between meals)?
Answer: During Fasting (between meals), epinephrine stimulates the use of fuel reserves. Question: What is the difference between Fed state (after a meal) and Fasting (between meals)?
Answer: The Fed state (after a meal) is a state where the priority is to supply sufficient glucose to the brain and RBCs and to preserve protein. During this state, glycolysis and aerobic respiration occur and insulin stimulates the storage of lipids, proteins, and glycogen. Fasting (between meals), on the other hand, is a state where the priority is to use fuel reserves. During this state, the major process is hepatic glycogenolysis and glucagon and epinephrine stimulate the use of fuel reserves.Question: What is the role of glycolysis during Fed state (after a meal)?
Answer: During Fed state (after a meal), glycolysis is one of the processes that occur.Question: What is the role of aerobic respiration during Fed state (after a meal)?
Answer: During Fed state (after a meal), aerobic respiration is one of the processes that occur.tab
