During glycolysis, one molecule of glucose is broken down into two molecules of _________________.

What is the name of the starting material that must be regenerated in the Calvin Cycle?

Short Answer Section (2 points each): Five questions are listed below. For full credit, you must answer three of the questions. If you choose to answer more than three, you will be given bonus points for each correct answer. What is the chemical reaction for cellular respiration? Briefly describe the structure of a photosystem. What is the chemical reaction for photosynthesis? Briefly describe the process of chemical cycling throughout an ecosystem. What are the three main steps of cellular respiration? Which step (if any) uses oxygen?

True or False: The two phases of glycolysis are the energy investment phase and the energy payoff phase.

What are the electron carriers used in cellular respiration?

True or False: NAD+/NADH is the primary electron carrier in photosynthesis.

Pigments are substances that absorb visible light. They absorb light as little packets of energy in fixed quantities called a __________________.

True or False: The Citric Acid Cycle indirectly fuels the creation of ATP by using the energy produced when electrons “fall down the chain” to set up an H+ gradient.

Cellular respiration is the process of harvesting chemical energy from organic molecules. It requires oxygen, therefore it is considered a(n) ___________________ process.

What are the two main products of the light reactions of photosynthesis that proceed to the Calvin Cycle?
