3.What molecules are responsible for transporting high energy electrons to the electron transport chain during cellular respiration?

Select one:

a.

NAD+ and FAD NAD+ and FAD

b.

H 2 0 and 0 2  H20 and 02

c.

NADH and FADH 2  NADH and FADH2

4.What phase of cell respiration produces the most ATP?

Select one:

a. ETC

b. Prep reaction

c. Krebs cycle

d. Glycolysis

 

Why do disaccharides produce more CO2 than monosaccharides?

Select one:

a. Disaccharides spontaneously break down and the cell needs to actively break down monosaccharides so their carbon dioxide production is slower.

b. They are made from two monosaccharides stuck together so they can be broken down into twice as much ethanol, carbon dioxide, and energy.

c. The bond that links the subunits of the disaccharides together is made of carbon dioxide, so when it is broken extra carbon dioxide is produced.

d. Disaccharides break down molecules at more than twice the rate that monosaccharides break down molecules.

b. 569.1 mg/min

c. 523.7 mg/min

d. 602.1 mg/min

 

What is the temperature of the Erlenmeyer flask?

Select one:

a. 21.5 K

b. 70.7 K

c. 294.6 K

d. 248.2 K
