Question

To enter the mitochondria, most fatty acids must be attached to:

A. UDP

B. CDP

C. carnitine

D. Fatty Acid Synthase I (FASI)

Electrons in the ETC move from:

A. Complex I to Complex II to Complex IIII to Complex IV

B. Complex I to Complex III to Complex IV

C. Complex II to Complex III to Complex IV to the ATP Synthase

D. Complex I, Complex II, Complex III and Complex IV to the ATP Synthase

Answer 1

QUESTION

Option A:-Incorrect

Reason:- UDP stands for uridine diphosphate. It is one of the most common carriers of sugar molecules along with CMP and GDP.

Option B:-Incorrect

Reason:-CDP stands for cytidine diphosphate. It is a carrier for diacylglycerol, phosphorylcholine during the synthesis of phospholipids.

Option C:-CORRECT

Reason:- The inner mitochondrial matrix is impermeable to fatty acids hence carnitine shuttle is needed to transport fatty acid from cytosol to the mitochondrial matrix.

Option D:-Incorrect

Reason:- FAS is a multienzyme in humans that catalyze the synthesis of palmitate from malonyl CoA and acetyl-CoA.
