Does chemiosmosis expend energy
Inanimate objects or systems, like a rock sitting still, do not expend energy.
The coupling of chemiosmosis to energy storage occurs in the process of cellular respiration, specifically during oxidative phosphorylation in eukaryotic cells. This process involves the generation of a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP by ATP synthase.
Yes, active transport requires the cell to expend energy in the form of ATP in order to move molecules against their concentration gradient. This process allows the cell to maintain proper concentrations of molecules inside and outside the cell.
The law of conservation of energy states that energy cannot be created or destroyed, only transformed. When we eat food, we consume a certain amount of energy (calories) that is then used by our body for various functions. If we consume more calories than we expend, the excess is stored as fat, whereas if we consume fewer calories than we expend, we lose weight as our body uses stored energy.
To calculate how long you need to exercise to expend 100 kcal at an energy rate of 270 W, first convert 100 kcal to Joules (1 calorie = 4.184 J), then divide the energy in Joules by the power in Watts to find the time in seconds. Finally, convert the time from seconds to minutes. In this case, you would need to exercise for approximately 44.3 seconds to expend 100 kcal at an energy rate of 270 W.
ATP synthase couples chemiosmosis to energy storage.

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].

Because you constantly expend energy.
When you expend the energy to complete that project.
An energy feed is a food source that gives extra energy to those who eat it, allowing them to expend more energy when needed.
Facilitated diffusion.

It doesn't require the cell to expend energy.
