True or false: metabolism is a controlled set of biochemical True
reactions that occur in living organisms in order to maintain
life.
True or false: enzymes slow down chemical reactions to false, they speed up (catalyze) chemical reactions
conserve energy
The term for metal ions that assist enzymes during the cofactors
catalysis reaction
What is catabolism? The process of breaking down larger molecules into useful energy sources
Upon cellular injury, which metabolic process is involved anabolism
during the growth and repair phases of the cell.
An organism that obtains its energy (derives ATP) from phototrophic microorganism
photons of light is called a __________________
An organism that derives its energy by removing electrons Lithotroph
from elemental sulfur would be classified as a
____________
Describe the energy transfer process relative to both ADP ATP has the energy (phosphate group) to donate, and ADP can accept energy in
and ATP 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 oxidative phosphorylation
chemotropic eukaryotes
The catabolism of a single molecule of glucose goes The breakdown of glucose goes through 1. glycolysis 2. fermentation or respiration
through what three transitions and then 3. electron transport chain ETC
True or false: in the absence of absence of oxygen false
fermentation produces 2 ATP
what is the primary byproduct of the TCA cycle select NADH and FADH2
True or false: in the absence of oxygen fermentation False, it does not produce any additional ATP
produces 2 ATP
True or false: the reactants of the TCA cycle directly enter False
and fuel the electron transport system
What are the main two roles of glucose 6 - phosphate in G6P 1. prevents glucose from diffusing out of the cell and 2. serves as a signal
the cell? molecule to the cell that glycolysis is about to begin.
