Question
Chapter 6.5, Problem 1TC
Summary Introduction
To explain:
How the response of circulation of blood to skin and sweating both resemble and differ from the mechanism of feedback inhibition of enzymes.
Introduction:
The feedback mechanism of an enzyme is an allosteric regulation where the final product present in the sequence of reactions is accumulated in higher quantity.

ACTIVITY 10.4.2
Explain your answer briefly but concisely.
What are the steps in the energy investment phase?
2. What are the steps in the energy-yielding phase?
3. What are the enzymes involved in an irreversible reaction? How
are these enzymes being activated? What about inhibited?
4. Which step in the glycolytic pathway would ensure that glucose
is fated for glycolysis?
5. During strenuous activity, the demand for ATP in muscle tissue is
vastly increased. In rabbit leg muscle or turkey flight muscle, the
ATP is produced almost exclusively by lactic acid fermentation.
ATP is formed in the payoff phase of glycolysis by two reactions,
promoted by phosphoglycerate kinase and pyruvate kinase.
Suppose skeletal muscle were devoid of lactate dehydrogenase.
Could it carry out the strenuous physical activity; that is, could it
generate ATP at a high rate by glycolysis? Explain.
6. The transformation of glucose to lactate n myocytes releases
only about 7% of the free energy released when…

A typical fat in the body is glyceryl trioleate, Cs-H10406. When it is metabolized in the body, it combines with oxygen to produce carbon dioxide, water, and 3.022 x
10 kJ of heat per mole of fat. Write a balanced thermochemical equation for the metabolism of fat. How many kilojoules of energy must be evolved in the form of
heat if you want to get rid of 15 pounds of this fat by combustion? How many nutritional calories is this? (1 nutritional calorie = 1 x 10° calories)

1. Baby is a 12 year old, 35 lb Beagle dog with a body condition score of 5/9. On
a routine visit to the vet to administer his annual vaccinations and get his teeth
cleaned, the owner questions whether he is giving Baby the right amount of
food. The energy density of the diet is 275 kcal ME per can.
• Calculate Baby's maintenance energy requirement (MER).
• How many cans of the diet should the owner give Baby per day?

This represents about 25 000 kcal, but is obviously protected i.e. used in starvation or caloric restriction ** Consider a large meal at ~1000 kcal, and 60% carbohydrate – that's 150 grams of CHO!
