Question

10 true or false 2 points
caloric content is obtained by burning food in calorimeter and measuring the resulting change in water temperature.
true
false

11 multiple choice 2 points
the mitochondrial specific activity responsible for atp production is called:
glycolysis
cellular respiration
aerobic metabolism
catabolism

12 multiple choice 2 points
the renal arteries deliver ______ of the total cardiac output every minute.
2%
100%
25%
80%

Explanation:

Analyze Question 10

The statement describes bomb calorimetry, where food is burned in a chamber surrounded by water to measure the heat released via the temperature change of the water.

$$ Q = m \cdot c \cdot \Delta T $$

This is the standard method for determining caloric content, making the statement true.

Analyze Question 11

The question asks for the mitochondrial specific activity responsible for ATP production.

• Glycolysis occurs in the cytosol.
• Aerobic metabolism is a broad term, but cellular respiration specifically encompasses the mitochondrial processes (citric acid cycle and oxidative phosphorylation) that generate the bulk of ATP.
• Catabolism is the general breakdown of molecules.

Thus, cellular respiration is the most accurate specific activity listed.

Analyze Question 12

The kidneys receive a substantial portion of the cardiac output to filter blood. Under resting conditions, the renal arteries deliver approximately 20% to 25% of the total cardiac output to the kidneys every minute. Among the choices, 25% is the correct value.
