Chemical work in cells is powered by the energy produced from chemical reactions, specifically the breakdown of molecules such as glucose through processes like cellular respiration. This energy is captured in the form of ATP (adenosine triphosphate) and utilized to drive cellular processes such as protein synthesis, active transport, and muscle contraction.

What of the following is true about chemical energy?
Chemical energy is a form of potential energy stored within the bonds of chemical compounds. It can be released through chemical reactions, such as combustion or metabolism, to produce heat and/or work.
Are most chemical reactions at equilibrium in living cells?
No, most chemical reactions in living cells are not at equilibrium. Cells maintain a dynamic balance, constantly adjusting reaction rates to respond to changing conditions and maintain homeostasis. Equilibrium is rare in living systems due to the constant flux of molecules and energy.
What happens to energy when matter undergoes a chemical change or a physical change?
A tiny bit of the sun's energy falls onto earth. On earth some of the solar energy is changed by photosynthesis into chemical energy stored in the carbohydrate molecules in plant cells.A human eats a plant. Or a human eats an animal that ate a plant. The chemical energy stored in the plant (or animal) cells is moved into the cells of the human's body. All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. Respiration takes place in every cell in your body.Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and heat. The muscle contracts, the legs push, and the body leaps into the air. Some of the chemical energy has now been changed into the kinetic energy of a body flying up into the air. The rest of the original chemical energy has been used to raise the temperature of your jumping body. If you keep jumping for long you'll get pretty hot.During a change, energy is either released or absorbed
What does chemical energy store mean?
Chemical energy storage refers to the potential energy stored within the chemical bonds of molecules. This stored energy can be released through chemical reactions, such as combustion, to produce heat and do work. Examples include the energy stored in gasoline, food, and batteries.
What is chemical energy and How do organisms make energy available for work?
Chemical energy is the potential energy stored in the bonds of chemical compounds. Organisms release this energy through processes like cellular respiration, where they break down molecules such as glucose to produce ATP, the energy currency of cells. ATP is then used to power cellular functions and work.
Is gasoline powered by sunlight?
No. Gasoline will work in the dark. Gasoline is powered by the chemical reaction that causes the flames when ignited.
Do vitamins work with minerals to initiate chemical reactions within cells?
Yes, vitamins can work with minerals as co-factors to help initiate chemical reactions within cells. For example, vitamin C can enhance the absorption of iron, a mineral that is essential for the production of red blood cells. Together, vitamins and minerals play important roles in supporting various cellular processes in the body.
The three main types of work that cells perform?
chemical work, transport work, mechanical work
What is an Electrical Chemical Engineer?
They work on chemical battery cells, for companies like Duracell and energizer.
Is it possible for a cell to harvest all of the energy contained within a chemical reaction to produce movement?
No, it is not possible for a cell to harvest all of the energy contained within a chemical reaction to produce movement. Some energy is always lost as heat during the conversion process. Additionally, there are limitations to how efficiently cells can convert chemical energy into mechanical work.
A chemical fuel that allows the body cells to do work and to function is known as?
ATP
What is another name for biological catalysts that speed up chemical reactions in organisms?
Enzymes are another name for biological catalysts that speed up chemical reactions in organisms.
What are three main types of work that cells perform and gives examples of each?
Cells perform three main types of work: chemical work, such as synthesizing molecules; mechanical work, such as muscle contractions; and transport work, such as moving ions across a membrane. Examples include protein synthesis, cell movement, and ion pumps in cell membranes.

Which calculator is more efficient a battery powered or solar powered one?
there both not bad exept for the battery opperated one you have to keep buying batteries and for the solar powered one you need solar cells to make it run like on a rainy day it wouldn't work good because you have to have the sun's energy XD. there both not bad exept for the battery opperated one you have to keep buying batteries and for the solar powered one you need solar cells to make it run like on a rainy day it wouldn't work good because you have to have the sun's energy XD.
