Activation energy
Energy required to get reaction started
Active site
Site for substrate to bind to
Active transport
Requires energy and against concentration gradient
Adenine
Complementary to thymine
ADP
Energy molecule
Aerobic
Reaction that requires oxygen
Alcohol
Product of anaerobic respiration/fermentation
Amoeba
Unicellular organisms
Anaerobic
Respiration without oxygen
ATP
High energy molecule
Catalyst
Lowers activation energy
Cell membrane
Forms the boundary between the cell and its surroundings
Cell wall
Provides rigidity and strength and supports the cell against changes in turgor
Cellular respiration
Supply cell with available energy from glucose and is therefore needed in active transport
Cellulose
The carbohydrate making up the substrate of the cell wall
Centriole
Involved in cell division and the organisation of spindle fibres
Chloroplast
The site of photosynthesis
Chromosome
Long strands with genes
Cilia
Anchored in the cell membrane and extending outside the cell used for motility
Coenzyme
Required by an enzyme to function
Cofactor
Required by the substrate so that the enzyme can catalyse the reaction
Concentration gradient
Difference in concentration and substances
Contractile vacuole
Involved in water regulation
Cristae
Site of electron transport
