QUESTIONS AND CORRECT VERIFIED ANSWERS
ALREADY GRADED A+ (BRAND NEW VISION)
exothermic reaction - ANS-a chemical reaction where energy is given off, so that the products
have less energy than the reactants.
endothermic reaction - ANS-a chemical reaction where energy is taken in, so that the products
have more energy than the reactants.
amylase - ANS-Enzyme that can break the bonds of starch to form the carbohydrate monomer,
glucose.
Denature - ANS-Characteristic of proteins; a change in shape that stops the protein from
functioning.
Allosteric - ANS-__________ regulation of enzyme occurs when a molecule binds to an enzyme
changing the protein's shape
Catalyst - ANS-______ an agent that speeds up a chemical reaction without itself being
permanently altered
Transition State - ANS-The less stable state that occurs and is usually a high-energy state
between reactants and products in a chemical reaction
, Substrate orientation - ANS-When Enzyme bring together specific atoms into a correct position
that are otherwise rotating and tumbling so that bonds can form
Protein Kinases - ANS-enzymes that reversibly activate or inactivate other proteins by adding
phosphate groups to (phosphorylating) them
Temperature - ANS-After looking at the shape of graph the enzyme activity of this enzymes is
being regulated by what variable:
Substrate Concentration - ANS-After looking at the shape of graph the enzyme activity of this
enzymes is being regulated by what variable:
Metabolism - ANS-The totality of an organism's chemical reaction
Bioenergetics - ANS-The study of how organisms manage their energy resources
Catabolic pathway - ANS-Release energy by breaking down complex molecules into simpler
ones i.e. Cellular respiration
Anabolic pathways - ANS-Consume energy to build complex molecules from simpler ones i.e.
Amino acids making up proteins
breaks down molecules, negative ΔG - ANS-Catabolic
Energy storing, Positive ΔG - ANS-Endergonic
builds larger products, Positive ΔG - ANS-Anabolic
