QUESTIONS WITH
CORRECT ANSWERS
Which is more complex in chemical structure (poly, di, or mono)? - Answer-
Polysaccharides
Cardiovascular exercise training is associated with which of the following? - Answer-
Increased mitochondria density
In gluconeogenesis, in the strictest of biochemistry definitions, the carbons found in the
"newly" formed glucose can not come from? - Answer-Carbohydrates
Red bloods cells produce their energy entirely by ________ resulting in them producing
and releasing
________. - Answer-Glycolysis, Lactate
Explain what is the reason with excessive fat/lipid metabolism that Ketone Bodies are
formed? - Answer-1. Beta oxidation results in excessive Acetyl CoA production
2. de novo lipogenesis is too slow of a process to eliminate the Acetyl CoA
3. Ketone formation is rapid
4. Ketones are above to dissolve quickly into fluids
5. Ketones can be eliminated in urine, expired air and sweat.
Explain the major differences between aerobic and anaerobic glycolysis. - Answer-1.
Aerobic G results in
cytosolic NADH+H being used for ATP production in mitochondria, ANA G does not, 2.
Aerobic G results
in pyruvic acid going to Acetyl CoA, in ANA G pyruvic acid become lactate
3. ATP yield in Aerobic G is
much larger than in ANA G
4. The rate of ATP production is faster in ANA G than Aerobic G
If you suffocate, the metabolic reason you die is due to? - Answer-Acidosis
, Why do we try and spare protein from use as an energy metabolism substrate? -
Answer-1. Proteins provide amino acids for the free amino acid pool in the body
2. The free amino acid pool is
utilized in protein synthesis throughout our body
3. Metabolizing protein for ATP results in a decreased
free amino acid pool
4. A decreased pool may mean protein synthesis is compromised affecting tissue
composition and function.
In glycolysis, Fructose-6-phosphate is converted to what in the next chemical reaction?
- Answer-Fructose-1,6-diphosphate
Process by which Ketone Bodies are formed? - Answer-Ketosis
Phosphoenol Pyruvate is part of which energy pathway? - Answer-Glycolysis
Which of the following is an enzyme in the Krebs Cycle and considered an integral
protein of the mitochondria? - Answer-Pyruvate dehydrogenase
The cytosolic NADH+H produced in skeletal muscle Glycolysis under __________
conditions is placed in the
mitochondria as __________. - Answer-aerobic; FADH2
NADH+H placed into the Electron Transport Chain is equal to approximately 3 ATP
under aerobic conditions. - Answer-True
The bioenergetics of aerobic ATP production from glucose is? - Answer-Less in skeletal
muscle cells than cardiac muscle cells
The First Law of Thermodynamics allows us to interconvert forms of energy - Answer-
True
In the Krebs Cycle the direct formation of ATP per "one turn" of the cycle is (hint, no
electron transport chain
involvement)? - Answer-1
A. Electron Transport Chain
B. Glycolysis
C. Krebs Cycle
D. Beta Oxidation
E. None of the above - Answer-1. Water formation = A
2. CO2 formation = C
3. Glucose 6-phosphate formation = B
4. Fumaric Acid = C
5. FAD formation = C
