During photosynthesis carbon dioxide is blank to glucose - CORRECT ANSWER-Reduced
What is the term for all chemical reactions that occur in a cell during growth and repair ? -
CORRECT ANSWER-Metabolism cofactors
Term used to describe the loss of an enzymes shapes so that it no longer functions caused by
extreme ph or temperature - CORRECT ANSWER-Denatured
What is an endergonic reaction ? - CORRECT ANSWER-Requires input of energy from other
sources
What is an exergonic reaction ? - CORRECT ANSWER-hydrolysis of ATP allowing the charge of
free energy to drive and do other processes
Difference between ADP and ATP - CORRECT ANSWER-ATP is unstable and has high potential
energy whereas ADP is stable and has lower potential energy than ATP
, Define aerobic respiration - CORRECT ANSWER-ATP to ADP, we need to lose a phosphate group
and we need a hydrolysis reaction
Define active transport - CORRECT ANSWER-Energy is required (endergonic)
In the enzymatically controlled chemical reaction A->B+C A is the ? - CORRECT ANSWER-
Substrate
What is active coenzyme during photosynthesis? - CORRECT ANSWER-NADP^+
What is the coenzyme active during aerobic cellular respiration? - CORRECT ANSWER-NADH
What are the three things ATP is used for ? - CORRECT ANSWER-Supplying energy needed to
synthesize macromolecules within the cell, energy needed to pump substances across the
plasma membrane, and muscles to contract, Cilicia and flagella to beat and chromosomes to
move
Why are enzymes absolutely necessary to the continued existence of the cell - CORRECT
ANSWER-Enzymes boost chemical reactions which are extracted from cells and catalyze
processes
What is an enzyme ? - CORRECT ANSWER-An enzyme speeds a molecules that speeds a
chemical reaction without it damaging itself
How is the ph environment of salivary amylase related to the rest of the progress of human
digestion ? - CORRECT ANSWER-Neutral ph but can withstand the stomach acid
What happens to salivary amylase in your stomach ? - CORRECT ANSWER-Starts breaking down
starch in the mouth and continues after it has passed down in the stomach or small intestine
