CELLULAR RESPIRATION AND
FERMENTATION
ATP energy!
Needed to: Build proteins Copy DNA Muscle contractions Nerve impulses Synthesizing
hormones
WHY DO ORGANISMS NEED TO RESPIRE
OVERVIEW OF AEROBIC RESPIRATION
Aerobic= “with air”
AEROBIC CELLULAR RESPIRATION
This process yields 36 ATP molecules!
THE LINK BETWEEN PHOTOSYNTHESIS AND CELLULAR
RESPIRATION
Glycolysis occurs in cytoplasm
Glyco= sweetLysis= to break
Results in 4 ATP per molecule of glucose
GLYCOLYSIS
The Kreb’s Cycle and Electron transport chain occur in the mitochondrion
Produces 32 ATP molecules
KREB’S CYCLE AND ELECTRON TRANSPORT CHAIN
OVERVIEW OF AEROBIC RESPIRATION
FERMENTATION
Also known as anaerobic respiration= “without air”
Bacteria in yogurt produce lactic acid
Animals experience muscle fatigue when lactic acid builds up
LACTIC ACID FERMENTATION
SACCHAROMYCES CEREVISIAE
This process yields 4 ATP for every glucose molecule
ALCOHOLIC FERMENTATION
SACCHAROMYCES CEREVISIAE
FERMENTATION
Also known as anaerobic respiration= “without air”
