You are studying a metabolic pathway and are trying to decide if it is an anabolic pathway or a catabolic pathway. Which of the following would help diagnose this problem? A) Look for common intermediates. B) Look for ATP-requiring steps. C) Look for enzymes under allosteric regulation. OD) All of the above. OE) None of the above.

What is the last electron acceptor? Which process will proceed with or without oxygen?

Why is energy required for nutrient transport? Give an example of a system that transports nutrients and describe what source of energy is used to move the nutrients into the cell. Why can’t most organisms use the nitrogen gas that is so prevalent in the atmosphere? How do these organisms acquire a usable form of nitrogen?

Organic forms of nitrogen are converted to inorganic forms via what process? a)photosynthesis b)consumption c)nitrogen fixation d)decomposition

Why do organisms using or living in the presence of oxygen need to eliminate these chemical species ( free radicals)? in reference to oxygen usage which organisms must produce enzymes that detoxify free radicals?

4) a)Fill in the blanks: When oxygen is the final energy carrier in the production of ATP, the process is called _________________. When an inorganic molecule is used to drive theoxidation in a cell to produce ATP, the process is called _______________.b)How is energy transferred to proteins in the process called phosphorylation?c) Fill in the blanks: When a molecule is oxidized it has (more/less) _________ electrons than it did before being oxidized. When a molecule is reducedit has (more/less)_________ electrons than it did before being reduced.d) Is NADH is the oxidized or reduced form of NAD+?

What are the steps in metabolic pathways, and can you use an example of how to explain metabolic pathways?
