Question
Chapter 13, Problem 4TQ
Summary Introduction
To review:
The reason for regulating of catabolism by environmental factors.
Introduction:
Catabolism is the breakdown of large complex molecules into smaller ones with the release of energy. Every cell carries out different types of catabolic reactions to obtain energy and substrate for biosynthesis. Catabolic reactions are affected by intrinsic factors, the concentration of reactants and products, and environmental factors.

In the table below, list the important products of the complete glycolysis of this molecule.
• In the first column of the table, write the chemical formula, name, or standard biochemical symbol for a product molecule. In the second column, write the
total number of these molecules produced.
Add Row
• Only list the important products, including (1) molecules with any of the carbon atoms originally in the molecule above, (2) energy storage molecules
(like ATP), and (3) any newly oxidized or reduced coenzymes.
•
List each product molecule on a separate row. You can add more rows to the table if you need them.
• Be sure you write the number of product molecules formed by the complete glycolysis of the molecule above.
• If the molecules does not undergo glycolysis at all, check the box under the table and leave the table blank.

The adduct acetoacetyl-acyl carrier protein is formed as an intermediate during fatty acid biosynthesis. The CO2 used to synthesize malonyl-S-CoA is lost. Would this help make the reaction more or less energetically favorable? A) Loss of CO2 increases entropy (AS) and therefore decreases the favorability of the reaction (AG). B) Loss of CO2 has no effect on entropy (AS) and therefore does not affect the favorability of the reaction (AG). C) Loss of CO2 increases entropy (AS) and therefore increases the favorability of the reaction (AG).
