Homework Answers
Answer – Option (C)
When muscle cells are at rest ATP remain plenty. And ATP to AMP ratio is high leading to high energy charge. High amount of ATP result in the favor of anabolic pathway. Anabolic is the constructive process and increase the body size by growth and cell differentiation. That’s why it is said that body made up during rest not at the time of gym.

10. What is the relationship between anabolic and catabolic pathways? A. Anabolic pathways create complex molecules using the energy from catabolic pathways. B. Anabolic and catabolic pathways are interchangeable. C. Catabolic pathways create complex molecules using the energy from Anabolic pathways. D. Molecules broken down by anabolic pathways provides energy for catabolic pathways. Cellular respiration 11. Which of the following statements about NAD+ is true?

20 AMP-activated protein kinase (AMPK) is an enzyme that is activated by high levels of AMP in cells. If levels of AMP are high in cells, that means that levels of ATP are low. Once active, AMPK activates catabolic pathways and inhibits anabolic pathways in the cell. Why do you think that is the case? Choose the answer that best explains the role of AMPK. 8 00:20:36 Multiple Choice O By activating catabolic pathways, AMPK provides a mechanism to activate...

Which of the following statements regarding catabolic pathways are true? 1. When proteins are used as a source of energy for the body, the proteins are first broken down to produce amino acids, which are then converted into either glyceraldehyde 3 phosphate or acety CoA The enzyme phosphofructokinase is subject to allostericinhibition by high levels of citric acid When acety CoA builds up in the call it increases the activity of the enzyme that synthesizes oxalacetato from pyruvate and carbon...

D 4. Which of the following is TRUE regarding the resting state of a neuron? There is more K+ outside of the neuron than there is inside of the neuron. During the resting state, all of the Na+ and K+ leaky channels are nonfunctional The H+-ATPase pump is responsible for establishing the resting electrochemical gradient in the neuron. The outside of the neural cell has a positive charge while the inside of the neural cell has a negative charge.
