Biology 101 Exam 2 Study Guide 2026 | Cellular Respiration &
Photosynthesis | Graded A+
1. What are the reactants in the chemical equation for photosynthesis?
Carbon dioxide and water
Oxygen and sunlight
Glucose and oxygen
Nutrients and minerals
2. In photosynthesis, what happens to the water?
Water gives up an electron becoming oxidized to oxygen
carbon dioxide
It is converted to ATP via the Calvin cycle
It takes part in the reaction but is unchanged
3. Describe the role of NADP+ in the process of photosynthesis.
NADP+ is involved in the breakdown of glucose during cellular
respiration.
NADP+ is a substrate for glucose synthesis in the Calvin cycle.
NADP+ acts as an electron carrier that is reduced to NADPH during
the light-dependent reactions.
NADP+ is produced as a byproduct of ATP synthesis.
4. What is the role of water in the process of photosynthesis?
Water is converted into oxygen gas.
Water is used to transport nutrients.
, Water is absorbed to create glucose.
Water is split to provide electrons and protons.
5. Describe the significance of water in photosynthesis and its contribution to
the overall process.
Water is used to create glucose directly during the Calvin cycle.
Water serves as a waste product in photosynthesis.
Water is primarily involved in the absorption of sunlight.
Water is essential in photosynthesis as it is split to release oxygen
and provide electrons for the light-dependent reactions.
6. If a plant is exposed to low light conditions, how would this affect its glucose
production and subsequent ATP generation in cellular respiration?
Glucose production would increase, enhancing ATP generation.
ATP generation would occur without glucose production.
Glucose production would decrease, leading to reduced ATP
generation during cellular respiration.
There would be no effect on glucose production or ATP generation.
7. What are the main products of cellular respiration when glucose is
metabolized?
ATP and glucose
Oxygen and glucose
NADH and oxygen
Carbon dioxide and water
