Does chemiosmosis expend energy
Yes, require to spend energy
Yes , Exocytosis is a part of active transport meaning it needs energy to move from concentration gradients.
Divide the energy by the power. You'll need to convert kcal to joule first. Then, if you divide joule by watt (which is equal to joule/second), the answer will obviously be in seconds.
If it is inefficient, causing more input then output, or wasteful, eg: a hydrogen converter with a reuptake adapter reusing purified hydrogen but losing the bulk of the material.
Does chemiosmosis expend energy
Yes ^that's not true. Actually work is not the rate at which you expend energy.
Expend is a verb which means to use up or consume. Sedentary office workers do not expend much physical energy on the job.
Try not to expend all of your energy during the early laps [of a race].
No. The cell does need to expend energy in order to perform its life functions.
Yes, require to spend energy
When you expend the energy to complete that project.
Because you constantly expend energy.

Passive Transports
An energy feed is a food source that gives extra energy to those who eat it, allowing them to expend more energy when needed.
This involves both the first and second laws of thermodynamics. According to the first law, the energy you expend must come from somewhere. You have to take in that energy in the form of the chemical energy contained in the food before you can expend energy to move yourself around, grow, heal, breath, etc. According to the second law, that energy will not flow into you spontaneously. You must expend energy to draw that energy into your body for use, in other words, you have to eat.
