cellular respiration Flashcards
breakdown of glucose to produce energy in the form of ATP
cellular respiration
is the reverse of photosynthesis and the cellular respiration equation is the reverse of photosynthesis
cellular respiration
3 Cycles of Cellular Respiration (produces 2 ATP, pyruvic acid, and NADH)
- glycolysis
- kreb’s cycle
- electron transport chain
2 types of Cellular Respiration
- Aerobic
- Anaerobic
first step in both aerobic and anaerobic respiration
glycolysis
Glucose breakdown/the breakdown of glucose
glycolysis
Doesn’t require oxygen and occurs in the cytoplasm; Produces 2 ATPs
glycolysis
Kreb’s Cycle produces ___ ATPS.
2
Electron Transport Chain (ETC) produces _____ ATPs.
32
After cellular respiration ____ ATPs will be created.
36
2 ATPs from Glycolysis + 2 ATPs from Kreb’s Cycle + 32 ATPs from ETC = 36 ATPs
2 ATPs from Glycolysis + 2 ATPs from Kreb’s Cycle + 32 ATPs from ETC = 36 ATPs
Properties of Aerobic Respiration
- takes place in the mitochondria
- uses pyruvic acid and NADH from glycolysis
- oxygen combines with hydrogen forming water reverse of what occurs during photosynthesis
- final products are CO2 H20 and 36 ATPs per molecule of glucose
- C6H12O6 + 6O2 + 6H2O + 36ATP
Properties of Anaerobic Respiration
- Anaerobic Respiration is the combined process of glycolysis and fermentation
- does not use oxygen to release small amounts of energy in a molecule called ATP
- Anaerobic Respiration is also called fermentation
- takes place in cytoplasm
yeast cells break down glucose to carbon dioxide, alcohol, and ATP
alcoholic fermentation
during periods of strenuous activity, muscles burn, and sting because glucose is broken down without oxygen-producing lactic acid
lactic acid fermentation (bacteria/animal cells)
Fermentation only produces _____ ATP per glucose.
2
There are 2 types of Fermentation
- Lactic Acid Fermentation
- Alcoholic (Ethanol) Fermentation
the breakdown of pyruvic acid without the use of oxygen (used when low oxygen is available)
fermentation
causes bread dough to rise
alcoholic (ethanol) fermentation
used to make yogurt, cheese, and bacteria (good bacteria)
lactic acid fermentation
combined processes of glycolysis and fermentation
Anaerobic Respiration
Yeasts are:
eukaryotic, single-celled, fungi
is used as fuel, and is a type of alcohol, the same type of alcohol found in alcoholic beverages
ethanol
