Does chemiosmosis expend energy?
No, chemiosmosis does not expend energy. Instead, it utilizes the energy stored in the form of a proton gradient to drive ATP synthesis in processes such as oxidative phosphorylation in mitochondria or photosynthesis in chloroplasts.
Does active transport require the cell to expend energy?
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.
How does the law of conservation of energy relate to eating and caloric intake?
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.
How long need to exercise to expend 100 kcal while expending the energy rate of 270 W?
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.
Does amoeba engulfs require energy?
Yes, engulfing requires energy because the amoeba must expend energy to rearrange its cytoplasm and membrane to surround and engulf the food particle. This process involves active transport mechanisms to move the engulfed material inside the cell.
Does chemiosmosis expend energy?
No, chemiosmosis does not expend energy. Instead, it utilizes the energy stored in the form of a proton gradient to drive ATP synthesis in processes such as oxidative phosphorylation in mitochondria or photosynthesis in chloroplasts.
Is it true that work is the rate at which you expend energy?
Yes ^that's not true. Actually work is not the rate at which you expend energy.
How do you use expend in a sentence?
Expend is a verb which means to use up or consume. Sedentary office workers do not expend much physical energy on the job.
How do you write a sentence with the word expend?
Try not to expend all of your energy during the early laps [of a race].
Why do you eat food daily?
Because you constantly expend energy.
When can you say when work is done?
When you expend the energy to complete that project.
What is energy feeds?
An energy feed is a food source that gives extra energy to those who eat it, allowing them to expend more energy when needed.
Cell must expend energy to transport substances using?
Facilitated diffusion.
What cell must expend energy to transport substances using?
Facilitated diffusion
Why is diffusion consider a passive transport?
It doesn't require the cell to expend energy.
Is fear an energy?
No - despite its representation as such in the Green Lantern comics, Fear is NOT an energy. It is an emotion that can cause someone to expend energy however.
What does a cell use to expend energy to transport substances?
Generally, cells derive their energy from ATP (in their phosphate bond).
