PHOTOSYNTHESIS What is it? CELLULAR RESPIRATION What is it? Reactants Products Factors Affecting Photosynthesis Anaerobic Respiration

Photosynthesis: What is it? § Turning light into food § Light-dependent reactions § (light energy is converted to ATP) § Light-independent reactions § (ATP powers the reaction to convert CO 2 to glucose) § Done by plants in the chloroplast

Respiration: What is it? § Turns food into energy in the presence of oxygen (aerobic) § Steps § Glycolysis § Kreb’s cycle § Electron transport chain (ETC) § Done by plants and animals in the mitochondria

Photosynthesis: Reactants § § § Uses… 6 CO 2 + 6 H 2 O + light energy (carbon dioxide + water + light)

Photosynthesis: Products § § § …to make C 6 H 12 O 6 + 6 O 2 (glucose + oxygen)

Respiration: Reactants § § § Uses… C 6 H 12 O 6 + 6 O 2 (glucose + oxygen)

Respiration: Products § § § …to make 6 CO 2 + 6 H 2 O + 36 ATP energy (carbon dioxide + water + 36 ATP)

Factors Affecting Photosynthesis § § § Increased sunlight… Increased CO 2… Increased H 2 O… § ALL lead to increased rates of photosynthesis!

Anaerobic Respiration § Anaerobic = no oxygen is present! § Lactic acid fermentation § Occurs in animals § Produces lactic acid, CO 2, & 2 ATP § Alcoholic fermentation § Occurs in yeast & bacteria § Produces alcohol, CO 2, & 2 ATP
