Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Name the physiological process that requires energy
A
Osmosis
B
Active transport
C
Respiration
D
Diffusion
Explanation: 

Detailed explanation-1: -Active transport of solute in plant refers to flow of solutes against a concentration gradient and therefore requires input of energy.

Detailed explanation-2: -Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. Energy for the process is acquired from the breakdown of glucose using oxygen in aerobic respiration. ATP is produced during respiration and releases the energy for active transport.

Detailed explanation-3: -Examples will include diffusion of gases across alveolar membranes and diffusion of neurotransmitters such as acetylcholine across the synapse or neuromuscular junction.

Detailed explanation-4: -ATP hydrolysis provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.
