Chapter 35, Problem 2AC
Summary Introduction

To determine:

The initial hopes of scientists when leptin was discovered after they found that excess leptin in blood does not reduce hunger or food intake.

Introduction:

Leptin is a peptide secreted by fat cells, and helps to regulate fat storage in mammals. Leptin secretions increase when fat storage “increases” and “decreases” when fat storage falls down to an optimum level.

Summary Introduction

To suggest:

An evolutionary explanation for leptin’s role in fat regulation.

Introduction:

Leptin is a hormone of energy expenditure; and is formed by adipose cells that help to regulate energy balance by inhibiting hunger.

Assume that you have genetically modified the gene for the glucagon receptor in a rat. Theextracellular region of the modified glucagon receptor can still bind to glucagon. However, thecytoplasmic region of the modified glucagon receptor can only bind and activate an inhibitoryG protein in response to glucagon binding. Describe how lipid metabolism in this geneticallymodified rat responds to starvation. Briefly explain your reasonings please
In order to normalize blood sugar levels after a meal, mammalian systems release insulin and rely on a different enzyme to phosphorylate glucose after it enters liver cells. Explain the mechanisms by which these two systems decreases blood sugar to safe levels.
Fatty acids from stored triacylglycerols (fat) are not available for gluconeogenesis. Speculate why we do not have the enzymes to directly convert fatty acids into glucose. Plants (especially seeds) do have enzymes to convert fatty acids into carbohydrates. Why are they so lucky?
