Question
Chapter 22, Problem 38P
Interpretation Introduction
Interpretation:
Role of decarboxylation in fatty acid synthesis must be determined.
Other
Concept introduction:
The process of fatty acid synthesis occurs in the cytosol of the animal cells, while it occurs in the stroma of chloroplast in the plant cells. It is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.

Instructions.
Given each set of information which may include common name(s) and the reaction catalyzed, you are required to identify the main class of the specific enzyme described.
Name: citryl-CoA synthetase
Reaction: ATP + citrate + CoA = ADP + phosphate + (3S)-citryl-CoA
Name: D-xylulose reductase
Reaction: xylitol + NAD+ = D-xylulose + NADH + H+
Name: cellobiose phosphorylase
Reaction: cellobiose phosphate = α-D-glucose 1-phosphate + D-glucose
Name: carbonic anhydrase
Reaction: H2CO3 = CO2 + H2O
Other info: The enzyme catalyzes the reversible hydration of gaseous CO2 to carbonic acid, which dissociates to give hydrogencarbonate above neutral pH.
Name: pantoate activating enzyme
Reaction: ATP + (R)-pantoate = AMP + diphosphate + (R)-pantothenate.
