Question

4 true or false 2 points
healthy kidneys will reabsorb virtually all organic nutrients, including glucose and amino acids.
true
false

5 multiple choice 2 points
which of the following cell types is primarily responsible for the synthesis and secretion of pepsinogen?
epithelial cells
mucous cells
chief cells
parietal cells

6 multiple choice 2 points
which process is considered part of \internal respiration\, in which oxygen is utilized to synthesize adenosine triphosphate (atp) for ?
the urea cycle
all of the above
pulmonary ventilation
oxidative phosphorylation
none of the above

Explanation:

Analyze Question 4

Healthy kidneys reabsorb virtually all organic nutrients, including glucose and amino acids, in the proximal convoluted tubule.

• Statement is True.

Analyze Question 5

Pepsinogen is an inactive zymogen secreted by gastric chief cells in the stomach.

• Chief cells: synthesize and secrete pepsinogen.
• Parietal cells: secrete hydrochloric acid and intrinsic factor.
• Mucous cells: secrete mucus.
• Correct option: Chief cells.

Analyze Question 6

Internal respiration (or cellular respiration) refers to the metabolic processes within cells where oxygen is used to generate ATP.

• Oxidative phosphorylation: the metabolic pathway in mitochondria that uses oxygen to generate ATP.
• Pulmonary ventilation: breathing (external respiration).
• Urea cycle: nitrogenous waste disposal.
• Correct option: oxidative phosphorylation.

• Parietal cells

Question 6

• the urea cycle
