Chapter 19, Problem 40CQ

(a)

Summary Introduction

To explain: The reason how carboxylase maximizes the efficiency of converting starch into oil.

Concept introduction:

An ester derived from glycerol and three fatty acids is called triacylglycerol (oil). It is the main storage of energy in most of the seeds. During the development of seeds, the oil is produced by using acetyl-CoA, which is derived from sucrose. The seed also contains RuBP carboxylase.
