cellular respiration Flashcards
(22 cards)
name the 2 types of respiration
anaerobic and aerobic
what is anaerobic respiration
respiration not requiring oxygen
what is aerobic respiration
respiration requiring oxygen
where does anaerobic respiration take place
the cytosol (liquid portion fo the cytoplasm)
what processes are involved in anaerobic respiration
glycosis
what is glycosis
the breakdown of a glucose molecule to pyruvic acid; it releases energy to form 2 molecules of ATP
what is ATP
adenosine triphosphate is a molecule that stores energy in cells; the energy is stored in the bond between the end phosphate group and the rest of the molecule.
what is ADP
adenosine diphosphate is the substance formed when the end phosphate group is removed from a molecule of ATP.
requirements of anaerobic respiration
glucose
wastes of anaerobic respiration
lactic acid
amount of ATP produced in anaerobic respiration
2 ATP
requirements of aerobic respiration
pyruvic acid (from glycosis) and oxygen
where does aerobic respiration take place
cytoplasm and mitochondria
what processes are involved in aerobic respiration
- glycosis
- citric acid cycle
- electron transport system
waste in aerobic respiration
carbon dioxide and water
how much ATP is produced in aerobic respiration
- glycosis = 2
- citric acid cycle = 2
- electron transport system = 34
where does the lactic acid travel to (anaerobic)
in the blood stream to the liver
what happens to the lactic acid once it is at the liver
combines with oxygen and converts back into glucose, repaying the oxygen debt.
when does aerobic respiration take place
when the respiratory system and circulatory systems keep up
when does anaerobic respiration take place
when the respiratory system cant keep up with the circulatory system?
what is cellular respiration
important metabolic process
organic molecules are taken in as food, are broken down to release energy from glucose for cells activities
what is the chemical equation for cellular respiration
C6H12O6 + 6O2 —-> 6CO2 + 6H2O + Energy
glucose + oxygen = carbon dioxide + water + ATP/heat
