UA BSC 108 EXAM 2 STUDY GUIDE 2026
VERIFIED QUESTION SET AND SOLUTIONS
◉ C4 photosynthesis
Answer: The two-stage photosynthetic pathway in which CO2 is first
fixed in mesophyll cells to form 4-carbon acids, and then the 4-
carbon acids are broken down into 3-carbon acids in the bundle
sheath cells
◉ Examples of C4 plants
Answer: sugarcane and corn
◉ Why do some plants use C4 photosynthesis?
Answer: It is an adaptation for hot and dry weather
◉ Photosynthesis
Answer: the process that stores energy in the form of glucose
◉ Cellular Respiration
Answer: the process that releases energy from glucose
◉ An oxidation reaction involves?
,Answer: the loss of electrons
◉ A reduction reaction involves?
Answer: the gain of electrons
◉ Glucose from food is converted to?
Answer: Co2, releasing energy that is used to produce ATP in the
process of cellular respiration
◉ Formula for cellular respiration in words
Answer: glucose + oxygen --> carbon dioxide + water + energy
◉ Formula for cellular respiration
Answer: C6H12O6 + 6O2 --> 6CO2 + 6H2O + 38ATP
◉ Aerobic respiration
Answer: Respiration that requires oxygen
◉ Anaerobic respiration
Answer: Respiration that does not require oxygen
◉ Which stage of cellular respiration requires oxygen?
, Answer: The electron transport chain
◉ Cellular respiration takes place in?
Answer: the mitochondria of all eukaryotic organisms
◉ Structure of Mitochondria
Answer: Outer membrane that covers the organelle and contains it
like a skin, the inner membrane which folds over many times and
creates layered structures called cristae, and the fluid contained
inside the mitochondria called the matrix
◉ Three stages of Cellular Respiration
Answer: glycolysis, the citric acid cycle (Krebs cycle), and the
electron transport chain
◉ Where does glycolysis take place during cellular respiration?
Answer: the cytosol of the cytoplasm
◉ Where does the citric acid cycle (Krebs cycle) occur?
Answer: the matrix of a mitochondrion
◉ Where does the electron transport chain occur?
Answer: the inner membrane of the mitochondrion
