AP Bio Unit 3

substrate

molecule that binds to a protein’s active site

active site

region where substate binds

enzyme

protein which speeds reactions and reduces activation energy, ending in -ase

factors affecting enzymes

temperature, pH, chemicals

photosynthesis

process that synthesizes glucose from solar energy

location of photosynthesis

chloroplast (green part of plants), spongy cells

stoma

co2 and o2 exchange

chloroplast structure

organelle in plan cells, makes sugar

where do plants get their energy?

ATP comes from sugar made in photosynthesis

pigments

absorb specific wavelengths of light

Chloroplast stroma: photons absorbed by?

chlorophyll, leading to oxidation

Chloroplast Stroma: h2o donates an electron to stabilize?

chlorophyll

Chloroplast Stroma: water splits into H+ and O2, creating

chemiosmosis gradient

Light Dependent Reaction occurs in

thylakoid

Light Independent Reaction occurs in

stroma
