Cell biology

Controls cell activity, DNA is also found

Controls entry and exit of materials

Site of protein synthesis

Site of aerobic respiration

Site of chemical reactions

Provides structural support to the cell

Site of photosynthesis in green plant

Contains cell sap (water, sugar, salt)

Contains bacterial DNA

Movements of substances like oxygen or carbon dioxide down a concentration gradient (high to low) (passive) no energy required

Movement of water molecules down a concentration gradient (high to low) passive (no energy required)

Movement of molecules against a concentration gradient (low to high) (active) requires energy and proteins in the cell membrane, ions move by active transport

Carries a complimentary copy from the DNA (in nucleus) to a ribosome where protein is made

Synthesis reaction

Degradation reaction

Enzymes are most active

High temperature
