Cellular Respiration Flashcards
What is Cellular respiration?
The process by which cells produce energy from glucose and oxygen
What are the reactants and products of cellular respiration?
Reactants: Glucose, oxygen
Products: Carbon dioxide, Water, ATP
What are the steps of cellular respiration?
- Glycolysis
- Prep Step
- Citric Acid Cycle
- Oxidative Phosphorylation
What do ATPs consist of?
Adenosine Triphosphate
How is ATP formed?
By phosphorylation of ADP with a free phosphate group
What is oxidation reaction?
Loss of electrons
What is reduction reaction?
Gain of electrons
Oxidative Phosphorylation
Coupling of electron transport from the electron carriers and ATP synthesis
What is ATP synthase
A power generator that acts like a turbine during ATP synthesis
What are the steps to Oxidative Phosphorylation?
Electron Transport Chain
ATP Synthesis
Explain Electron Transport Chain
Electrons move down electron transport chain,
energy released is used to pump H+ across membrane
Explain ATP Synthesis
H+ flows through ATP synthase enzyme
Energy released used to phosphorylate ADP
what is glycolysis?
Metabolic pathway that converts glucose into pyruvic acids
What’s the result of Glycolysis
2 ATP and 2 NADH
What are the inputs for glycolysis accounting?
1 Glucose
2 ATP
2 NAD+
Does anaerobic respiration use oxygen?
No
How is ATP produced when anaerobic respiration takes place?
By glycolysis only
Is the mitochondria involved during anaerobic respiration?
No
Is fermentation Anaerobic or aerobic?
Anaerobic
Fermentation regenerates _______ so glycolysis can continue
NAD+
Alcohol Fermentation happens when _______ is converted into ethanol and CO2
Pyruvic Acid
Lactic Acid fermentation happens when ________is converted into lactic acid
Pyruvic acid
_________ Acumulation in the muscle tissue reduces pH, which causes the stinging feeling when exercising
Lactic Acid
What are the primary energy supplies of the cell?
Carbohydrates
