The plant cell
A catalyst helps chemical reactions occur.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell.
These are not chemical reactions but thermonuclear reactions.
acidic and basic conditions occur due to what reactions in the body
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
It supports the organelles of the cell and is a part of the cell's structure. Chemical reactions also occur in the cytoplasm.
No, chemical reactions can be endothermic or exothermic.
Cooking and burning involve chemical reactions.
In a vacuum
We call this collection of chemical reactions metabolic reactions or metabolism.
