Signal transduction pathways are involved in regulating carbohydrate metabolism. Which of the following statements is false?

Group of answer choices

When blood sugar is high, insulin signaling inhibits gluconeogenesis and activates glycolysis by decreasing fructose-2,6-bisphosphate synthesis.

Epinephrine binding to its receptor results in phosphorylation and inactivation of glycogen synthase.

Glucagon stimulates an increase in blood glucose levels by activating glycogen breakdown and stimulating gluconeogenesis.

Insulin signaling results in the activation of phosphatases, which remove phosphate from glycogen phosphorylase and reduces glycogen breakdown.

Glucagon signaling stimulates the formation of cAMP whereas insulin signaling reduces cAMP levels.

1. Try to answer the following questions as accurately as possible

a) There are about 15 or so mechanisms by which metabolism can be controlled at different levels. which are the 15 mechanisms by which metabolism can be controlled?

b) identify three mechanisms that can control metabolism with immediate effect

c) identify three mechanisms that require more time to exert their effects

d) Humans have 4 isoenzymes that differ in how they function. why do we need 4 isozymes?

e)  How are phosphofructokinase-1 and fructose 1,6-bisphosphatase regulated?

f) 7 reactions in glycolysis are used in the reverse direction in gluconeogenesis. How can this be?

Chapter 7: How Cells Harvest Energy

• Interpret the role of electrons, electron carriers, and ATP in energy metabolism
• Explain the purpose of oxygen in respiration
• Describe where in the cell and where in mitochondria each process of cellular respiration happens
• Summarize the initial reactants, final products and outcomes of glycolysis, pyruvate oxidation and Krebs cycle. In this summary, track the carbons, the electrons and the ATP produced.
• Illustrate the purpose of the electron transport chain, where those electrons come from and where do they end up.
• Contrasts the two mechanisms for producing ATP and their relative efficiency.
• Distinguish the process and the outcomes between aerobic and anaerobic respiration
