Respiration - Elethu Flashcards
Raw materials needed for cellular respiration
Glucose
Oxygen
Products of cellular respiration
Carbon dioxide
Water
ATP (energy)
Where does cellular respiration take place
first phase in the cytoplasm outside mitochondrion
second and third takes place inside mitochondrion
Define Aerobic respiration and Anaerobic respiration
Aerobic - Requires oxygen
Anaerobic - Doesn’t require oxygen
Name the three stages in Aerobic respiration
Glycolysis
Krebs cycle
Oxidative phosphorylation
Krebs Cycle
The citric acid cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
Kreb Cycle Steps
The eight steps of the citric acid cycle are a series of
- redox
- dehydration
- hydration
- decarboxylation reactions.
Oxidative Phosphorylation
- occurs on cristate of mitochondria
- energy rich H-atoms are transferred from 1 hydrogen acceptor to the next.
- the final hydrogen acceptor is oxygen forming H2O
Anaerobic respiration in the muscle during exercise
During vigorous exercise, muscles do not receive enough oxygen
only glycolysis takes place
glucose is broken down
small amount of energy is released
pyruvic acid is converted into lactic acid, which releases in muscle cells
What is Lactic acid
a toxin that leads to muscle stiffness and muscle pain
Anaerobic respiration in plants
glycolysis occurs glucose is broken down pyruvic acid is formed small amount of energy is released pyruvic acid is broken down carbon dioxide is released alchol is formed
What is the process called or known as in the anaerobic respiration
Alcholic fermentation
