Photosynthesis Quiz

%%Photosynthesis%% occurs in cell organelles called the chloroplast.

In the %%light-dependent%% stage of photosynthesis, light energy is used to make two molecules; NADPH and ATP.

ATP and NADPH require light, therefore they are called %%light-dependent reactions.%%

The Calvin Cycle (light-independent stage) of photosynthesis is the process where ATP, NADPH, and CO2 are used to make sugars.

The thylakoid membrane contains pigments, the most common being %%chlorophyll%%.

%%Chlorophyll%% absorbs red and blue light and reflects green.

%%Chlorophyll%% is part of the two systems that convert light energy into chemical energy. These systems are called photosystems.

%%RuBisCo%% is an enzyme that fixes carbon from the atmosphere.

%%RuBisCo%% is the most important enzyme in the world because it makes life out of air.

%%RuBisCo%% is the most abundant enzyme.

Hydrogen Ions from water move through an enzyme, %%ATP Synthase%%.

%%ATP Synthase%% adds a phosphate to a molecule called ADP to make %%ATP%%.

%%ATP%% is used as an energy source for many chemical reactions in cells.

%%ATP%% = cellular energy.

%%Autotrophs%% get their energy from “self.”

%%Autotrophs%% get their energy from sunlight.

Autotrophs use light energy to synthesize organic molecules.

%%Heterotrophs%% get their energy from “eating others.”

%%Heterotrophs%% are consumers of other organisms.

%%Heterotrophs%% consume organic molecules.

%%Heterotrophs%% depend on %%autotrophs%%.

The %%chemical equation for photosynthesis%% is 6CO2 + 6H2O + light energy = C6H16O6 + 6O2

Oxygen is a byproduct of %%photosynthesis.%%

Reactants = products.
