AP Bio - Unit 3 Midterm

What is ATP

• main energy source that cells use for most of their work

• molecule that ATP becomes when it gives up one of its three phosphate groups

• a coenzyme that is an electron carrier

• Requiring molecular oxygen, O2

acetyl CoA

• molecule formed from the oxidation of pyruvate

• another name for the citric acid cycle

• a reduced coenzyme similar to NADH, an electron carrier

• A substance that absorbs visible light.

light reactions

• Metabolic processes carried out by green plants and cyanobacteria, by which visible light is trapped and the energy used to convert CO2 into organic compounds.

• The initial phase of photosynthesis, in which light energy is converted into chemical energy.

• Any of several green pigments associated with chloroplasts or with certain bacterial membranes; responsible for trapping light energy for photosynthesis.

• A graph of light absorption versus wavelength of light; shows how much light is absorbed at each wavelength.

Catalyst

• A chemical agent that speeds up a reaction without being consumed by the reaction.

• The amount of energy needed to push the reactants over an energy barrier.

• A chemical agent that speeds up a reaction without being consumed by the reaction.

• States that the enzyme and substrate undergo conformational changes to interact fully with one another

Chemical Energy

• the substance an enzyme catalyzes, changes.

• Describes an enzyme's maximum activity when every active site is being used.

• When a reaction doesn't require energy to proceed it is said to be this - doesn't mean it will be FAST.

• Potential energy trapped in molecular bonds.

After looking at the shape of graph the enzyme activity of this enzymes is being regulated by what variable:

• Protein Kinases

• Temperature

• Substrate Concentration

• Substrate Orientation

Substrate Orientation

• an agent that speeds up a chemical reaction without itself being permanently altered

• After looking at the shape of graph the enzyme activity of this enzymes is being regulated by what variable:

• enzymes that reversibly activate or inactivate other proteins by adding phosphate groups to (phosphorylating) them

• When Enzyme bring together specific atoms into a correct position that are otherwise rotating and tumbling so that bonds can form

When a reaction doesn't require energy to proceed it is said to be this - doesn't mean it will be FAST.

• Spontaneous Reaction

• saturated enzyme

• Competitive inhibition

• Chemical Energy
