Citric Acid Cycle

Question 1

Upon entering the mitochondrion via active transport pyruvate is first converted to a compound called acetyl coenzyme or acetyl CoA

Answer 1

Acetyl Coenzyme

Question 2

The junction between glycolysis and the citric acid cycle is accomplished by a multi-enzyme complex that catalyzes three reactions…

Answer 2

Pyruvate carboxyl group (-COO-)
Acetate
Coenzyme A (CoA)

Question 3

Already fully oxidized and thus has little chemical energy is removed and given off as a molecule of CO2
First step

Answer 3

Pyruvate carboxyl group (-COO-)

Question 4

Remaining two-carbon fragment is oxidized forming acetate
An enzyme transfers extracted electrons to NAD+ storing energy in the form of NADH

Answer 4

Acetate (ionized form of acetic acid)

Question 5

Sulfur-containing compound derived from a B vitamin attached to the acetate by unstable bond that makes the acetyl group very reactive

Answer 5

Coenzyme A (CoA)

Question 6

German British biologist physician and biochemist
Largely responsible for working out the pathway in the 1930’s

Answer 6

Hans Adolf Kreb

Question 7

Cycle functions as a metabolic furnace that oxidizes organic fuel derived from pyruvate

Answer 7

Krebs Cycle

Question 8

The formation of ATP from ADP and a phosphorylated intermediate
Amount of ATP that is generated by glycol is relatively low

Answer 8

Substrate-level phosphorylation

Question 9

is a type of chemical reactions that involves a transfer of electrons between species

Answer 9

Redox Reactions

Question 10

Krebs cycle number of process

Answer 10

8 step process

Question 11

Krebs cycle takes place in the?

Answer 11

Matrix of Mitochondria under aerobic condition
