Intigration Of Metabolism

Question 1

Fat cannot be made into

Answer 1

Glucose

Question 2

TCA cycle mainly provides precursors for what process

Answer 2

Gluconogenesis

Question 3

During fed state what is happening

Answer 3

Storing glycogen

Making TAG

Making protein

Some gluconogenesis

(Storing everything)

Question 4

During early fasting state what is happening

Answer 4

First place body takes from to maintain blood glucose is the glycogen stores

Cori cycle (lactate sent to liver for gluconogenesis)

Glycogenolysis and gluconogenesis upregulated

TAG lipolysis not active

Question 5

During starvation state what is happening

Answer 5

Sparing of protein

Increase lipolysis

Producing ketone bodies

Upregulated gluconogenesis

Question 6

During metabolic stress insulin is?

What does this mean?

Answer 6

insulin secretion is increased

which means no production of ketone bodies

Question 7

What is the significance of no ketone production during metabolic stress

Answer 7

FA cannot be used for energy

So mainly protein is degraded

Question 8

What is the priority of metabolic stress

Answer 8

wound repair and host defense at the expense of body tissues

Question 9

Some AA can be synthesized into

Answer 9

Fat and carbs

Question 10

What does pyruvate dehydrogenase do?

Answer 10

Convert pyruvate to Acetyl CoA (non-reversible)
