Delgado Biology 1406 Lecture Exam 3
Latest Updated Graded A+
Activation Energy - ANSWER-the minimum quantity of energy that the reacting species
must possess in order to undergo a specified reaction
Allosteric Regulation - ANSWER-regulation of an enzyme by binding an effector
molecule at a site other than the enzyme's active site
Anabolism - ANSWER-BUILDING!! refers to the process which builds molecules the
body needs; it usually requires energy for completion (endergonic reaction)
ATP-ADP Cycle - ANSWER-the continuously ongoing "energy recycling," through
oxidative phosphorylation of "low energy" ADP molecules, to "high energy" ATP
molecules (binding energy), and the subsequent hydrolysis of ATP molecules back to
ADP (releasing energy), facilitated by a complex series of biochemical processes called
cellular respiration
Catabolism - ANSWER-BREAKING!! refers to the process that breaks down complex
molecules into smaller molecules; it usually releases energy for the organism to use
(exergonic reaction)
Cellular Respiration Equation - ANSWER-C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
(as ATP)
Competitive Inhibitors - ANSWER-enzyme inhibition that works by binding at the active
site on the enzyme and compete with substrate for the active site and prevent the
substrate from binding
(structure is similar to that of the substrate since they are binding at the same site)
Endergonic vs exergonic reactions - ANSWER-Endergonic means absorbing energy in
the form of work whereas Exergonic means releasing energy in the form of work
How does pH affect enzyme activity? - ANSWER-As pH increases, enzyme activity
increases until it reaches an optimal point in which enzymes denatures and as pH
increases, enzyme activity decreases
How does temperature affect enzyme activity? - ANSWER-Enzymes work best at body
temperature. At lower temperatures, there is not enough kinetic energy for the reaction.
At higher temperatures, enzymes become denatured.
Inputs & Outputs of Electron Transport Chain - ANSWER-Input: 10 NADH + H+ 2
FADH2
Output: 10 NAD+ 2 FAD H2O 34 ATP
