new lec 5 and 6 after beta oxidation

Question 1

is glucose highly polar? what does this cause in relation to cell membrane

Answer 1

yes, cannot enter cell membrane by itself, need transporter proteins in order to get in

Question 2

can glycolysis occur under anaerobic conditions?

Answer 2

yes

Question 3

where does glyclolysis occur

Answer 3

in the cytosol

Question 5

what is the main thing that happens in prepatory phase?

Answer 5

ATP used to phosphorylate and activate glucose

Question 6

what is main thing that happpens in pay off phase

Answer 6

net generation of ATP

Question 7

What determines the metabolic fate of pyruvate?

Answer 7

The metabolic fate of pyruvate depends on the available route to oxidize NADH formed in glycolysis.

Question 8

why must NADH need to be oxidized back to NAD after being converted?

Answer 8

For the reaction to occur as an ongoing process

Question 9

what occurs in the cori cycle?

Answer 9

During recovery from excercise, some lactate from muscles is transported to the liver, where the liver converts it back to glucose through a pathway called gluconeogenesis. glucose then returns to be stored as glycogen

Question 10

what is the only step of TCA cycle that forms a C-C bond?

Answer 10

step 1, acetyl coa with oxaloacetate to citrate
