VERIFIED ANSWERS LATEST UPDATE
(2024/2025) GUARANTEED PASS
1. What is metabolism, catabolism and anabolism?:
Metabolism: All Chemical processes in the body. Conversion of
food into energy.
Catabolism (Exergonic= energy released): Breaking down
complex chemicals ex.
Digestion
Anabolism (Endergonic= energy consumed): building complex
chemicals (Protein Synthesis)
2. Explain the role of ATP in anabolism and catabolism::
Catabolic reaction:
-Energy is given OFF in the
form of ATP -The rest is
released as Heat
BIO256 EXAM
,Anabolic reaction:
-Energy & ATP is used
-Some heat is released
3. *Digestion in the GI tract is Catabolic or Anabolic?:
Catabolic (Break down) 4. Carbohydrate metabolism is
mostly _______ metabolism: Glucose metabolism
5. **Dietary sources of carbs: -Monosaccharides: 1 unit of
glucose
-Disaccharides: 2 units of monosaccharides, EX: Sucrose
-Polysaccharides: a bunch of monosaccharides together EX:
Starch, glycogen, and cellulose-plant structural carb that humans
cannot break down.
6. When glucose is low, one way it can be formed is by...
breaking down cell membranes
breaking down cell walls
breaking down starch breaking
down glycogen: breaking down
glycogen

BIO
Feedback:
Glycogen is a polymer of glucose and is broken down to its
glucose monomers as an energy source when glucose
concentration is low.
7. The oxidation of glucose to produce ATP is called?:
Cellular respiration
-Catabolic process in which energy is released
8. The body’s use of glucose breakdown primary purpose?:
ATP production for energy
9. **What are the 4 steps of cellular respiration?: -glycolysis=
break down of glucoses
-formation of acetyl coenzyme A
-Krebs cycle reaction
-electron transport chain reactions= The step that produces the
most ATP
10. *How many ATP's are net gained during glycolysis?: 2
ATP's
BIO256 EXAM
, 11 Aerobic vs Anaerobic Respiration: -These are the 2
methods of creating ATP:
Aerobic: with oxygen
-Results in greater ATP production
-Anaerobic: Without oxygen
-Glycolysis can proceed as it does not require oxygen
-Results in lesser ATP production
-Glucose is reduced to 2 lactic acid
12. Glycolysis: location, substrate, end product, how many
ATPs, anaerobic or aerobic?: -Location: Cytoplasm
-Substrate (starting material): Glucose molecule
-End product: 2 Pyruvate. Products: 2 ATP, 2 NADH + 2H
