BIO 110 Unit 2 Exam Questions with
Verified Answers
In which plant structure does photosynthesis primarily occur? - ANSWERSleaf
The raw materials or reactants of the photosynthetic process include -
ANSWERScarbon dioxide and water.
NADPH and ATP are used in the - ANSWERSCalvin cycle reactions.
We often say that we need food for energy. In a biological sense, is this correct? -
ANSWERSYes, 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? - ANSWERSDuring photosynthesis, oxygen
is used.
The substance that initially traps solar energy in photosynthesis is -
ANSWERSchlorophyll
Which of the following is a byproduct of photosynthesis? - ANSWERSoxygen
Most enzymes are - ANSWERSprotein molecules.
What are the two sets of reactions for photosynthesis? - ANSWERSlight reactions,
Calvin cycle reactions
What is the value of photosynthesis to humans? - ANSWERSIt will reduce the amount
of carbon dioxide in the atmosphere.
The place where the substrate fits onto the enzyme is called the - ANSWERSactive site.
Which energy association is correct? - ANSWERSKinetic energy is energy of motion.
Which statement most accurately describes the second law of thermodynamics? -
ANSWERSEnergy cannot be changed from one form to another without a loss of usable
energy.
At the cellular level, photosynthesis occurs within - ANSWERSthe chloroplast.
, Raising the temperature generally __________ the rate of an enzymatic reaction. -
ANSWERSincreases
The various uses of ATP include all of the following except - ANSWERSbeing a
structural component of the cell membrane.
What are the products of photosynthesis? - ANSWERSoxygen and carbohydrate
Most cells use a tremendous amount of ATP, - ANSWERSbut the amount of stored ATP
is not great because our body constantly generates ATP from ADP + P.
Any energy transformation involves the loss of some energy as - ANSWERSheat
The function of an enzyme is to - ANSWERSincrease the rate of a metabolic reaction.
In a eukaryotic cell, the electron transport system occurs in the -
ANSWERSmitochondrion
The products of cellular respiration are - ANSWERScarbon dioxide, water, and ATP.
How many molecules are formed from the cleavage of glucose during the first step of
glycolysis? How many carbons are found in the resulting molecules? - ANSWERS2
molecules, each with 3 carbons
Glycolysis of a glucose molecule - ANSWERSproduces a net gain of two molecules of
ATP.
Alcoholic fermentation - ANSWERSAll of the answer choices are correct.
During glycolysis molecules of glucose are - ANSWERSbroken down by enzymes to
form two molecules of pyruvate.
The Krebs cycle produces - ANSWERSATP, NADH, and FADH2.
Pyruvate is converted to a two-carbon acetyl group attached to coenzyme A (CoA), and
CO2 is given off. This phase is called - ANSWERSthe preparatory reaction.
Plants are net - ANSWERSO2 producers and CO2 consumers.
Which of the following statements about glycolysis is true? - ANSWERSGlycolysis
breaks glucose down to 2 pyruvate molecules.
Which molecules are the products of aerobic respiration? - ANSWERScarbon dioxide
and water
Animals are net - ANSWERSO2 consumers and CO2 producers.
