Cellular Respiration and Fermentation

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”
