Chapter 5-Cellular Respiration Flashcards
Slow Twitch
Aerobic, cellular respiration, many mitochondria, more myoglobin, darker, longer lasting
Oxidation and Reduction (OIL RIG)
Oxidation Is Loss, Reduction Is Gain (of hydrogen)
Glycolysis
- Function
- Location
- Presence of oxygen
- Products
- Splitting sugars
- Cytoplasm
- Anaerobic, w/o oxygen
- ATP (2), NADH (2), Pyruvate
Aerobic
Needs oxygen
Krebs, citric acid Cycle
- Function
- Location
- Presence of oxygen
- Products
- Carbon dioxide and most electron carriers formed
- Matrix
- Aerobic
- ATP (2), Carbon Dioxide (6), NADH (8), FADH_2 (2)
Myoglobin
Iron and oxygen binding protein found in mammal muscles. High levels=can hold breath longer
Name poison and function
Rotenone, cyanide, carbon monoxide-blocks electron transport chain
Fast Twitch
Anaerobic, lactic acid fermentation, few mitochondria, less myoglobin, lighter, shorter lasting
Redox reaction
Moving electrons from one molecule to another, moving hydrogen ions
Oxidative Phosphorylation (ETC)
ATP formed as result of electron transfer from NADH or FADH_2 to O_2 by electron carriers
Cellular Respiration (and Equation)
Process that releases ATP by breakdown of glucose w/ oxygen
Sugar+Oxygen=Carbon Dioxide+Water+ATPs
3 Stages of Aerobic Respiration
Glycolysis, Krebs/ citric acid cycle, electron transport chain
Electron Transport Chain
- Function
- Location
- Presence of oxygen
- Products
- Oxidative phosphorylation and chemiosmosis involved, most ATP created
- Cristae
- Aerobic, uses oxygen
- ATP (32-34), water
Chemiosmosis (ETC)
Movement of ions across membane down concentration using concentration gradient
Substrate Level Phosphorylation
Enzyme transfers phosphate directly to ADP, forms ATP
Used in Glycolysis, Krebs Cycle
