Question

1. Which of the following is NOT true about glucagon?

Glucagon decreases triacylglycerol synthesis

Glucagon increases triacylglycerol synthesis

Glucagon is secreted in response to low blood glucose levels

Glucagon causes the liver to convert stored glycogen into glucose

2.

In the absence of oxygen, pyruvate from glycolysis cannot be further utilized for energy synthesis through the Krebs cycle because......?

Glycolysis becomes more energetically favorable than the Krebs cycle, thus pyruvate circulates through glycolysis for energy synthesis

Oxygen drives the entrance of pyruvate into the Krebs cycle

Oxygen is needed to react with pyruvate and convert it to acetyl CoA

ADH cannot donate electrons to ETC and so NAD+ is not formed and won’t push pyruvate to convert into acetyl CoA
