Metabolism - ANSWER all chemical reactions in the body
Types of metabolic pathways - ANSWER catabolic and anabolic
Catabolic pathways - ANSWER Large molecules are broken down into small ones.
Energy is released.
Anabolic pathways - ANSWER Small molecules are assembled into large ones.
Energy is required
Catabolic equation - ANSWER Respiration: C6H12O6 +6O2 —> 6CO2+6H2O + Energy
Anabolic equation - ANSWER Photosynthesis: 6CO2+6H2O + Energy —> C6H12O6
+6O2
Process of a competitive enzyme inhibitor - ANSWER - Has a structure similar to
substrate
- competes with the substrate for active site, inhibitor binds to active site of enzyme,
reactants cannot bind to enzyme; reaction doesn't occur
Enzymes - ANSWER biological catalysts
1
, What is the role of enzymes? - ANSWER speed up chemical reactions
How do enzymes work? - ANSWER Lower activation energy needed to start a
chemical reaction. Able to do this because they're reusable
Process of the NON-competitive enzyme inhibitor - ANSWER - Binds enzyme at
other location
- changes shape of enzyme; shape of active store is changed, reactants cannot bind to
enzyme; reaction does not occur
ATP - ANSWER Energy currency for cells
Role of ATP - ANSWER It's the energy used for biological activity (ex. Muscle
movement)
Metabolic processes result in the production of ATP - ANSWER Aerobic Respiration
— glucose is broken thanks to oxygen in order to produce ATP
Autotrophs - ANSWER an organism that uses energy (light & chem) to converts
inorganic C to glucose
Photoautotrophs - ANSWER use light energy (plants)
Chemoautotrophs - ANSWER use chemicals (organisms in hot springs or at the
bottom of the ocean)
Heterotrophs - ANSWER obtain organic carbon and nutrients by consuming other
organisms
