Summary Introduction

To propose: A mechanism for the activity of caffeine that accounts for the increase in alertness and sleeplessness.

Introduction: Epinephrine is a hormone secreted by the adrenal glands in response to stress. It reaches to the target cells through the blood and binds to its cell-surface receptors called G-protein coupled receptors. After binding, intracellular signaling cascade begins.

Plants in the genus Ephedra have been harvested for their active substance ephedrine for centuries. Ephedrine is used to reduce the symptoms of bronchitis and asthma, as a stimulant and study aid, and as an appetite suppressant. It is also the main ingredient in the illegal production of methamphetamine. Since 2006, the sale of ephedrine and related substances has been limited and monitored in the United States. One effect of ingesting ephedrine is greatly increased metabolism, which has been known to kill users of ephedrine. How might an increased metabolic rate cause death?
Given insulin's structure, where is its target likely located? Insulin's adverse side effects include headache, nau- sea, hunger, confusion and weakness. What can these symptoms be attributed to? Insulin has major effects on muscle and adipose tissue. It increases the rate of glucose transport across the cell membrane, decreases the rate of lipolysis, and increases uptake of triglycerides and some amino acids from the blood. In doing so, what metabolic processes does it favor? Carbohydrates: Lipids: Proteins:
Epinephrine stimulates glycogen breakdown by activating glycogen phosphorylase. However, in the research lab, no glycogen breakdown occurred when epinephrine was added to a test tube containing the enzyme and its substrate, glycogen. Explain why glycogen phosphorylase could be activated by epinephrine only when the hormone was added to intact cells in a solution.
