Question

Envision two areas of a cell separated by a membrane permeable to glucose. Glucose is at a higher concentration in area "A" than area "B". In which direction is at thermodynamically favorable for glucose to move? A) from area A to area B B) from area B to area A C) both directions are favorable D) both directions are unfavorable

Answer 1

Answer:  option B

The fact that is thermodynamically favourable shows that it involves the expenditure of heat.Then energy must have been consumed as ATPs, for the transport to occur.Thus  active transport is needed, to move the glucose against the concentration gradient from area B of lower concentration  to  A of high concentration.

Basically the transport of substances  with the use of ATPs from medium of lower concentration to medium of higher concentration against the concentration gradient is called Active transport.Heat energy is liberated from the expenditure of energy.
