Are most chemical reactions at equilibrium in living cells?
No because A chemical reaction that is at equilibrium in living cells is not capable of doing any work
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 chemical in Drano makes it work?
Caustic Soda
How can you find work at Chemical Abstracts Service?
If you are looking for work at Chemical Abstracts Service, you should go online to the CAS website. It offers information on jobs which are available to you.
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?
Different nutrients are important in different chemical reactions; this question is really too broad to answer.
The three main types of work that cells perform?
chemical work, transport work, mechanical work
Are most chemical reactions at equilibrium in living cells?
No because A chemical reaction that is at equilibrium in living cells is not capable of doing any work
What is an Electrical Chemical Engineer?
They work on chemical battery cells, for companies like Duracell and energizer.
What is another name for biological catalysts that speed up chemical reactions in organisms?
Enzymes act as catalysts.They catalyze within cells. Our bodies would not work without these enzymes.
A chemical fuel that allows the body cells to do work and to function is known as?
ATP
What are three main types of work that cells perform and gives examples of each?
there are prokaryotic and eukaryotic cells. Prokaryotic cells are in plants and do photosynthesis, while eukaryotic cells are in animals cells and they just help the organism stay alive. i hope this helped you guys :)
What relationships exist between an enzyme catalyst?
they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells. they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells.

Energy to power cellular respiration is supplied by what?
ATP is a direct source of energy when it comes to doing cellular work. ATP stands for Adenosine triphosphate. It is responsible for transporting chemical energy within the cells for the purpose of metabolism.
