Respiration begins with what step?
glycolysis
cells gradually release energy from glucose in a process called?
glycolysis
Fermentation occurs in animals and is called what?
lactic acid fermentation
fermentation in animals
lactic acid fermentation
what is formed in fermentation
lactic acid, or alcohol
What can stop glycolysis
large amounts of ATP cause cells NAD molecules to be filled with electrons
what does lactic acid do to muscles?
makes them sore and ache
where does glycolysis occur?
mitochondrion
Which reactant in cellular respiration was produced as a by product of photosynthesis?
oxygen
glycolysis breaks glucose into what?
pyruvic acid
glycolysis produces what molecule from glucose?
pyruvic acid
Lactic Acid Fermentation equation
pyruvic acid + NADH = lactic acid + NAD + Energy
2H atoms and one CO2 molecule are removed from
pyruvic acid and acetic acid
Aerobic Respiration
requires molecular oxygen
this process releases this amount of energy
small
define respiration
the breaking down of glucose for energy
Air apces that are found in bread are from
yeast running out of oxygen
