- Which of the following is not a product of the Kreb’s cycle?
- ATP
- NADH
- FADH2
- Pyruvate
- Which of the type of transport moves molecules across a membrane, against a concentration gradient, and requires the use of ATP?
- Facilitated diffusion
- Active transport
- Simple diffusion
- Osmosis
Homework Answers
ANSWER
- After glycolysis, pyruvate has to be converted to acetyl CoA by the enzyme pyruvate dehydrogenase complex, for it to enter the Kreb's cycle. Pyruvate is a part of Kreb's cycle , in a way, but is not a product of it. Therefore, the correct answer is option D.
- Active transport works against the concentration gradient and needs energy through ATP. Therefore, among the options given, option B is the correct answer.

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

A correct distinction between facilitated diffusion and active transport of a substance across a biological membrane is that . . . A. active transport requires conformational changes in the transport protein associated with the transport process, and facillitated diffusion does not. B. active transport requires integral membrane protein to carry out the transport, and facillitated diffusion does not. C. facilitated diffusion depends on an existing energy gradient acting on the transported substance, while active transport makes such a gradient. D....
