BIO 110 UNIT 2 EXAM QUESTIONS AND ANSWERS | COMPLETE BIOLOGY UNIT 2
STUDY GUIDE 2026/2027
In which plant structure does photosynthesis primarily occur? - ANS ✔✔leaf
The raw materials or reactants of the photosynthetic process include - ANS ✔✔carbon dioxide and
water.
NADPH and ATP are used in the - ANS ✔✔Calvin cycle reactions.
We often say that we need food for energy. In a biological sense, is this correct? - ANS ✔✔Yes, because
the food we eat has potential energy in its structure and this chemical energy can be converted into
mechanical energy.
Which of the following statements is false? - ANS ✔✔During photosynthesis, oxygen is used.
The substance that initially traps solar energy in photosynthesis is - ANS ✔✔chlorophyll
Which of the following is a byproduct of photosynthesis? - ANS ✔✔oxygen
Most enzymes are - ANS ✔✔protein molecules.
What are the two sets of reactions for photosynthesis? - ANS ✔✔light reactions, Calvin cycle reactions
What is the value of photosynthesis to humans? - ANS ✔✔It will reduce the amount of carbon dioxide in
the atmosphere.
The place where the substrate fits onto the enzyme is called the - ANS ✔✔active site.
Which energy association is correct? - ANS ✔✔Kinetic energy is energy of motion.
Which statement most accurately describes the second law of thermodynamics? - ANS ✔✔Energy
cannot be changed from one form to another without a loss of usable energy.
At the cellular level, photosynthesis occurs within - ANS ✔✔the chloroplast.
Raising the temperature generally __________ the rate of an enzymatic reaction. - ANS ✔✔increases
The various uses of ATP include all of the following except - ANS ✔✔being a structural component of the
cell membrane.
What are the products of photosynthesis? - ANS ✔✔oxygen and carbohydrate
Most cells use a tremendous amount of ATP, - ANS ✔✔but the amount of stored ATP is not great
because our body constantly generates ATP from ADP + P.
