311 metabolism quiz ACTUAL QUESTIONS
AND CORRECT ANSWERS
what are the two components of metabolism? - Correct answers✔catabolism and anabolism
Catabolism - Correct answers✔breakdown of large molecules (proteins, lipids carbohydrates)
into smaller ones; energy is released.
Anabolism - Correct answers✔synthesis of larger molecules from smaller ones, energy is
absorbed.
linear pathway - Correct answers✔series of reactions that generates a final product different from
any of the reactants
cyclic pathway - Correct answers✔the last step regenerates a reactant for the first step
ATP - Correct answers✔(adenosine triphosphate) main energy source that cells use for most of
their work
difference between controlled stepwise oxidation of sugar and simply burning it... - Correct
answers✔allows for the capture of useful energy, has lots of small steps with activation energies
overcome by enzymes instead of a singular large activation energy that is overcome by heat.
hydrolysis of ATP - Correct answers✔cleaves one phosphate group causing the formation of
ADP, releasing energy. water is a required reactant
, Phosphorylation of ADP - Correct answers✔phosphate added to ADP, the bond requires energy
(7.3kcal/mol) to form. Occurs in ATP synthesis and water is made in the reaction
what is the most oxdised form of carbon - Correct answers✔CO2
Oxidation is the - Correct answers✔loss of electrons, or a loss of a hydrogen or a gain of an
oxygen
reduction is the - Correct answers✔gain of electrons or a gain of a hydrogen or a loss of an
oxygen
When sugars, proteins and Fats are oxidized: - Correct answers✔- NAD is reduced to NADH, it
gains electrons in the form of H
- FAD is reduced to FADH2, it gains electrons in the form of H
reducing agent - Correct answers✔The electron donor in a redox reaction NADH, it gets
oxidized
oxidizing agent - Correct answers✔The electron acceptor in a redox reaction NAD+, it gets
reduced
amylase - Correct answers✔Enzyme in saliva that breaks the chemical bonds in starches to break
them into monosaccharides, breakdown will continue in the small intestine
