EXAM QUESTIONS
QUESTION 1
Glycolysis
CORRECT ANSWER
Splitting of glucose into 2 pyruvate, no oxygen required, occurs in the cytoplasm. Yields 2 ATP
RATIONALE: Glycolysis is the correct answer because it specifically refers to the metabolic pathway that splits glucose into
two pyruvate molecules in the cytoplasm, a process that occurs without the need for oxygen and yields a net gain of two
ATP molecules. The key characteristics of glycolysis, including its location in the cytoplasm and requirement for no oxygen,
distinguish it from other cellular respiration pathways such as the citric acid cycle and oxidative phosphorylation.

, QUESTION 2
Krebs Cycle
CORRECT ANSWER
Starts with 2 pyruvate, ends with CO2 and high energy electrons (NADH and FADH2) Produces 2 ATP and
occurs in the mitochondria; matrix
RATIONALE: The key concepts that make the statement about the Krebs Cycle correct are the intermediate steps and
products that occur within the citric acid cycle, which is another name for the Krebs Cycle, and the fact that it takes place in
the mitochondrial matrix. The mention of high energy electrons (NADH and FADH2), pyruvate conversion to acetyl-CoA, and
the production of CO2 and 2 ATP molecules accurately describe the essential processes and outcomes of the Krebs Cycle.
QUESTION 3
Electron Transport Chain
CORRECT ANSWER
Starts with high energy electrons from NADH and FADH2. 2 electrons are needed to move the H+ to the inter
membrane space. ATP synthase rotated and converts ADP to ATP. Creates 34 ATP molecules
RATIONALE: The statement is correct because it accurately describes the electron transport chain's role in generating ATP
through the process of chemiosmosis, where the energy from high-energy electrons is used to pump protons across the
mitochondrial membrane and drive the production of ATP. The specific mention of NADH and FADH2 as electron donors, the
requirement of 2 electrons to move H+ ions, and the production of 34 ATP molecules are all key components of the
electron transport chain's mechanism.
QUESTION 4
Anaerobic
CORRECT ANSWER
Without oxygen
RATIONALE: The term "anaerobic" refers to a process or environment that does not require oxygen, which is in contrast to
aerobic processes that rely on oxygen. The prefix "ana-" means "without" or "in the absence of," so the correct answer is
"Without oxygen" because it accurately conveys the absence of oxygen that is characteristic of anaerobic conditions.
QUESTION 5
Aerobic
CORRECT ANSWER
With oxygen
RATIONALE: The term "aerobic" refers to the presence of oxygen in a process, such as cellular respiration, where oxygen is
used to convert glucose into energy. By indicating that oxygen is required, the term "aerobic" distinguishes it from
anaerobic processes that do not rely on oxygen.

, QUESTION 6
Phosphagen System
CORRECT ANSWER
provides phosphate from ADP to become ATP and creatine is created. ATP loses a phosphate to create ADP
with creatine kinases and creates phosphcreatine.
RATIONALE: The correct answer describes the phosphagen system's primary function, which is to rapidly regenerate ATP
through the reversible reaction between ADP, creatine phosphate, and creatine kinase, allowing for high-intensity, short-
duration energy production in muscle cells. This process enables muscles to generate rapid bursts of energy without the
need for oxygen, highlighting the phosphagen system's role in anaerobic energy production.
QUESTION 7
Alcohol Fermentation
CORRECT ANSWER
Starts with pyretic acid and yields alcohol and co2... does not occur in human cells and occurs in the
cytoplasm of bacteria. Created 2 ATP with no oxygen
RATIONALE: This answer correctly describes alcohol fermentation because it highlights the biochemical pathway that
involves the conversion of pyruvic acid into alcohol and carbon dioxide, a process that occurs in the absence of oxygen and
produces energy in the form of ATP. The fact that it occurs in the cytoplasm of bacteria and not in human cells is also
accurate, as human cells primarily use aerobic respiration to generate energy, whereas anaerobic bacteria use fermentation.
QUESTION 8
Lactate Fermentation
CORRECT ANSWER
Starts with Pyruvate and ends with lactate, Yields 2 ATP occurs in the cytoplasm of a cell and does not need
oxygen.
RATIONALE: Lactate fermentation is a type of anaerobic respiration that occurs in the cytoplasm of cells, specifically in
muscle and red blood cells, where pyruvate is converted into lactate to regenerate NAD+ and produce a small amount of
ATP. This process is essential for energy production in low-oxygen environments, such as during intense exercise, when
aerobic respiration is not sufficient to meet the cell's energy demands.
