Bio 210 Exam 2 study guide Questions and
Answers 100% Solved
What is allosteric inhibition of enzyme activity? a molecule stops the activity of an
enzyme by entering a secondary site (an allosteric site) which changes the shape of the active
site blocking access for the substrate
What is feedback control of enzyme activity? Regulation of enzyme activity by the end
product of a pathway.
Photoautotrophs Organisms that produce their own food using light energy.
Chemoautotrophs Organisms that produce their own food using energy obtained from
chemical reactions.
Heterotrophs Organisms that obtain energy by consuming organic substances.
, Is the photosynthesis reaction anabolic or catabolic? Can you state the reason? Anabolic
process that converts light energy into chemical energy stored in glucose.
Reactants and products of photosynthesis Reactants: carbon dioxide and water;
Products: glucose and oxygen.
Major reactions of photosynthesis Light-dependent reactions and light-independent
(Calvin Cycle) reactions.
Components of the chloroplast involved in photosynthesis Thylakoid membrane, stroma,
chlorophyll, and other pigments.
What is the energy carrier during the light reaction? NADPH
Products of the light reaction Oxygen, ATP, and NADPH.
Where is the ATP produced during the light reaction? thylakoid membrane
