NEWEST VERSION 2025 ACTUAL EXAM COMPLETE QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS 100%GUARANTEED PASS!!!
True or false: metabolism is a controlled set of biochemical reactions that occur
in living organisms in order to maintain life. - DETAILED ANSWER -True
True or false: enzymes slow down chemical reactions to conserve energy -
DETAILED ANSWER -false, they speed up (catalyze) chemical reactions
The term for metal ions that assist enzymes during the catalysis reaction -
DETAILED ANSWER -cofactors
What is catabolism? - DETAILED ANSWER -The process of breaking down larger
molecules into useful energy sources
Upon cellular injury, which metabolic process is involved during the growth and
repair phases of the cell. - DETAILED ANSWER -anabolism
An organism that obtains its energy (derives ATP) from photons of light is called
a __________________ - DETAILED ANSWER -phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur
would be classified as a ____________ - DETAILED ANSWER Lithotroph
, Describe the energy transfer process relative to both ADP and ATP - DETAILED
ANSWER -ATP has the energy (phosphate group) to donate, and ADP can accept
energy in the form of a phosphate group. Thus, ATP can be dephosphorylated
(ATP-----> ADP + Pi), while ADP can be dephosphorylated into ATP (ADP + Pi ----->
ATP)
This phosphorylation process occurs in the mitochondria of chemotropic
eukaryotes - DETAILED ANSWER -oxidative phosphorylation
The catabolism of a single molecule of glucose goes through what three
transitions - DETAILED ANSWER -The breakdown of glucose goes through 1.
glycolysis 2. fermentation or respiration and then 3. electron transport chain ETC
True or false: in the absence of absence of oxygen fermentation produces 2 ATP -
DETAILED ANSWER -false
what is the primary byproduct of the TCA cycle select - DETAILED ANSWER -NADH
and FADH2
True or false: in the absence of oxygen fermentation produces 2 ATP -
DETAILED ANSWER -False, it does not produce any additional ATP
True or false: the reactants of the TCA cycle directly enter and fuel the electron
transport system - DETAILED ANSWER -False
