Question

Problem 31

Answer 1

Background and context

Active transport is a type of transport in which molecules use energy molecules in the form of ATP to travel against a concentration gradient. Primary active transport and secondary active transport are the two categories of active transportation based on the energy source employed. Energy is directly produced from ATP breakdown in primary active transport, while energy is derived from stored energy in the form of the stored energy of difference in ionic concentration between the two sides of the membrane in secondary active transport.
