Term
Aerobic Respiration
Definition

-Occurs with oxygen present

-Occurs in the mitochondria

-Produces 32-34 ATP's

Major Rxns:

intermediate step

kreb's cycle

electron transport chain

MORE EFFICIENT THAN ANAEROBIC resp.

Term
Anaerobic Respiration
Definition

-no O's present

-occurs in cytoplasm

-2 ATP's

Major Rxns:

fermentation- alcoholic and lactic acid

-less efficient than aerobic

Term
BOTH AEROBIC and ANAEROBIC ARE PRECEDED BY GLYCOLYSIS
Definition
Term
LACTIC ACID FERMENTATION
Definition

-produces 2 lactic acids, 2 ATP's, and 2 NADH's

-occurs in muscle cells and certain bacteria

-pyruvate to lactic acid, or 3 carbon to 3 carbon

-lactic acid buildup causes muscle soreness

-involved in dairy products

Term
ACOHOLIC FERMENTATION
Definition

-produces 2 ethanols, 2 CO2's, 2 ATP's, and 2 NADH's

-certain bacteria and yeast cells do this

-pyruvate to ethanol and co2

-3c to 2c + 1c

-involved in beer, wine, and bread

Term
BOTH LACTIC ACID AND ALCOHOLIC FERMENTATION OCCUR IN THE CYTOPLASM, START WITH GLYCOLYSIS, AND ARE ANAEROBIC!!!
