OXYGEN CONCENTRATION. It is required for respiration/to oxidize respiratory substrates to release energy required for active transport. an increase in oxygen concentration causes a simultaneous increase to the rate of active transport upto a certain level.
PH Enzymes being protein in nature are PH specific. Extreme change in PH affect the rate of respiration which is controlled by enzymes and may denature the enzymes reducing the rate of active transport. -GLUCOSE CONCENTRATION. is the main respiratory substrate for energy production. An increase in glucose concentration in cells increase the rate of respiration and hence the rate of active transport is increased upto a certain optimum level beyond which any additional increase in glucose concentration has no effect.
TEMPERATURE. The process of respiration by which energy for active transport is generated is controlled by enzymes. Enzymes work best at temperatures of between 350c-400c,usually called optimum temperature ranges. At very low temperatures enzymes are inactive lowering the rate of respiration hence low rates of active transport . increase in temperature above optimum ( above 400c)denatures enzymes slowing down respiration and ac tive transport until it finally stops.
ENZYMES INHIBITORS. They are substances which slow down (by competing with the enzyme for
the active sites in the substrate) or stop ( by blocking the active sites of the enzyme) the activity/funtioning of enzymes .this slows down or stops respiration and so is active transport.
CONCENTRATION OF CARRIER MOLECULES IN THE CELL MEMBRANE. They are
substances that bind to the ions being transported actively and carrying them across the membrane . increase in concentration
