Cell Chemistry Flashcards
Function of enzymes
Enzymes accelerate, or catalyse chemical reactions
What is an enzyme
Enzymes are complex protein molecules which act as biological catalysts.
Balanced chemical equation photosynthesis
6CO2 + 6H2O –( sunlight , chlorophyl ) –> C6H12O6 + 6O2
Balanced chemical equation aerobic respiration
C6H12O6 + 6O2 —-> 6CO2 + 6H2O + energy
All living things get their energy through a reaction called
Respiration
When there is no oxygen or limited oxygen,the respiration process is
Anaerobic
What is aerobic respiration ?
It is the most common form of respiration and requires oxygen. It produces energy, carbon dioxide and water vapour
Define catalyst
A catalyst is something that speeds up a chemical reaction without itself being used up in the reaction
Define anaerobic
Anaerobic respiration requires no oxygen and occurs in some yeasts and bacteria.
Fermentation
Anaerobic respiration in yeast, also known as alcoholic fermentation, enzymes in yeast convert glucose to ethanol
