What is required for the 'uphill transport' of substances through a membrane?
1 ATP
2 CTP
3 TTP
4 GTP
Explanation:
Active transport uses energy -ATP to transport and pump molecules against a concentration gradient.

Movement of molecules, from a region of higher concentration to a region of lower concentration with no expenditure of energy is called as
1 Osmosis
2 Active transport
3 Diffusion
4 None of them
Explanation:
Diffusion is the process in which movement of molecules occurs along the concentration gradient, i.e. movement of molecules takes place from its higher concentration to lower concentration without the expenditure of energy.

Diffusion rate is affected by
1 Concentration gradient
2 Pressure and temperature
3 Membrane permeability through which it occur
4 All of them
Explanation:
Diffusion is very important to plants since it is the only means for gaseous movement within the plant body.

The rate of diffusion of any substance is not affected by
1 Gradient of concentration
2 Presence of other substances in the solution
3 Molecular size of substances
4 Temperature and pressure
Explanation:
The diffusion rate depends on the size of the substances; obviously smaller substances diffuse faster. The diffusion of any substance across a membrane also depends on its solubility in lipids, the major constituent of the membrane.It is never depended on the presence of other substances in the solution.
