How is glucose realesesd
When glucose is broken down, bonds are broken, and this releases energy.
What processes require energy
Protein synthesis Cell division Muscle contraction Transmission of nerve impulses
Stage one of respiration
Glucose is broken down into 2 molecules of pyruvate in the cytoplasm. This happens in the absence of oxygen Located in the cytoplasm 2 atp
Stage 2 of aerobic respiration
If oxygen is present, aerobic respiration takes place. Each pyruvate is broken down to carbon dioxide and water. Located in the mitochondria A large amount of atp is produced
What is fermentation
Fermentation in animals is the breakdown of glucose in the absence of oxygen.
fermentation in animal cells
the pyruvate molecules are converted to lactate. Cytoplasm Number of ATP produced: 2
Fermentation in plants and fungal cells
Fermentation in plants and fungal cells is the breakdown of glucose in the absence of oxygen. Cytoplasm 2 atp
Fermentation in plant and fungal cells product
Ethanol and carbon dioxide. This reaction is not reversible due to the loss of carbon dioxide.
Fermentation in animal cells product
The product of this reaction is Lactate. reaction is reversible,lactate can be converted back into pyruvate in the presence of oxygen.
