NDT EXAM 3 REVIEW QUESTIONS AND
CORRECT ANSWERS VERIFIED
2025/2026.
Which organ breaks compounds and releases energy out into the body? - ANS The liver
What is energy metabolism? - ANS How the body obtains and uses energy from food
What is the difference between anabolic and catabolic reactions? - ANS Anabolic: makes
glycogen, triglycerides and proteins, require energy. Catabolic: breaks down glycogen,
triglycerides and proteins, releases energy.
What is ATP? - ANS High-energy compound that powers all activities in our cells and other
living things.
What is a coupled reaction? - ANS When energy is simultaneously consumed by reactions as
energy is produced. It is maintaining a state of equilibrium.
Why are enzymes and coenzymes so important to metabolism? - ANS Because they help to
break down the macros. Each enzyme has a specific job and our cells can create a pathway
depending on what enzymes are available. Coenzymes are important because without it, our
enzymes cannot function.

, What are the differences between Pyruvate and Acetyl CoA? - ANS Pyruvate: 3 carbon
structure that CAN make glucose. Acetyl CoA: 2 carbon structure that CANNOT make glucose.
What metabolic system changes glucose to pyruvate? - ANS Glycolysis
If we need energy quickly, what will pyruvate turn into? And what type of reaction is it? -
ANS Turns to lactate, and it's an anaerobic reaction. Pertains to the Cori Cycle. It's able to
provide ATP fast, lactate will accumulate in the muscles, making them sore.
If we have a slower need for energy, what will pyruvate turn into? And what type of reaction is
it? - ANS Turns to Acetyl CoA and it's an aerobic reaction.
One glucose makes how many pyruvates and acetyl CoA? - ANS 2, after the glucose converts
into either, the action is irreversible.
What two compounds can glycerol be converted into? - ANS Glucose or pyruvate
Fatty acids can be turned into what? - ANS Acetyl CoA
Deamination removes the __________ from an amino acid. This process must happen before
amino acids can do what? - ANS Nitrogen; enter the metabolic pathway.
How are amino acids able to make glucose? - ANS Because they're converted into pyruvate
What is energy balance? - ANS Energy in = Energy out
What will an energy imbalance cause? - ANS Weight changes
How many calories are in one pound of fat? - ANS 3500 kcals
