ANSWERS | GRADED A+.
What is cellular metabolism? - (ANSWER)Cellular metabolism is a set of
biochemical reactions that occur in living organisms to maintain life.
What is the primary function of enzymes and how are they regulated? -
(ANSWER)Enzymes speed up chemical reactions and they are regulated by a co
factor.
What is the difference between catabolism and anabolism? -
(ANSWER)Catabolism is the breaking down of larger molecules into energy
sources where anabolism is the building up of macromolecules from smaller
molecules.
ATP has the energy to _______ while ADP has the capacity to _________ energy. -
(ANSWER)ATP has the energy to DONATE while ADP has the capacity to ACCEPT
energy.
Chemotrophs can be subdivided into what two subgroups? -
(ANSWER)Chemotrophs can be divided by organotrophs and lithotrophs.
Organotrophs remove electrons from organic molecules such as glucose.
Lithographs remove electrons from inorganic molecules.
, Chemotrophs utilize which form of phosphorylation? - (ANSWER)Chemotrophs
use oxidative phosphorylation. Oxidative phosphorylation utilizes the energy
released by the chemical oxidation of nutrients to reform ATP.
What are the three distinct stages in the catabolism of glucose? -
(ANSWER)Glycolsis is the first step and yields 2 molecules of ATP.
Fermentation or respiration, 2 additional molecules of ATP can be produced.
Last, the electron transport chain produces 34 ATP via oxidative phosphorylation
event at the plasma membrane.
What are the reactants of glycolysis? - (ANSWER)The reactants are any molecules
present and involved at the beginning of glycolysis.
The reactants of glycolysis are glucose, NAD+ and ATP.
The reactants are everything located at the left of the arrow.
What are two main strategies for replenishing cellular concentrations of NAD+
and when are these strategies utilized? - (ANSWER)Fermentation and respiration
are the two strategies used by cells to convert NADH back to NAD+.
