Question 1

step one of krebs cycle

Answer 1

Oxaloacetate is combined with the acetyl coA

Question 2

Step two of krebs cycle

Answer 2

Citrate is isomerized into isocitrate

Question 3

Step three of krebs cycle

Answer 3

Isocitate is oxidized, making alpha ketogluterate and reducing NAD+ to NADH

Question 4

Step four of krebs cycle

Answer 4

Isocitate is oxidized, making alpha ketogluterate and reducing NAD+ to NADH

Question 5

Step four of krebs cycle

Answer 5

Alpha ketogluterate is decarboxylated and oxidized (forming nad+ to nadh) the resulting molecule is combined with coenzyme A making succinyl coA

Question 6

Step five of krebs cycle

Answer 6

Succinyl coA is turned into succinate, releasing coEnzyme a and making GTP

Question 7

Step six of krebs cycle

Answer 7

Succinate is oxidized into fumerate,

Question 8

Step seven of Krebs cycle

Answer 8

Fumerate is converted to malate

Question 9

Step eight of Krebs cycle

Answer 9

Malate is oxidized to oxaloacetate and reduces nad+ to nadh
