IDENTIFICATION: proposes that an enzyme and its substrate have rigid, complementary shapes that must fit together perfectly for the enzyme to catalyze a chemical reaction.
(a)
IDENTIFICATION: The process that plants converts light energy into chemical energy.
(a)
IDENTIFICATION: The process of breaking down glucose in the absence of oxygen.
(a)
IDENTIFICATION: the molecule that stores and transfers energy within cells, often called the “energy currency” of life. (FULL NAME)
(a)
IDENTIFICATION: a molecule essential for metabolism, linking the breakdown of carbohydrates, fats, and proteins to the citric acid cycle/Krebs Cycle to produce energy.
(a)
IDENTIFICATION: The phase of photosynthesis that fixes carbon dioxide into glucose molecules.
(a)
IDENTIFICATION: molecules that reduce or block the activity of enzymes, slowing down or stopping the reactions they catalyze.
(a)
The type of metabolic process that breaks down molecules to release energy.
(a)
