Enzymes
At least 2 of the reactants must change their chemical formula.
Cooking involve a chemical change.
A fire is a chemical change due to the irreversible changes that happen.
No chemical change happens, though a consequential change probably will.
Depending on the chemical change, sometimes color change, or appearance of bubbles.
the chemical shall be changed
no.
Cooking involves chemical changes.
The system remain unchanged.
The chemical properties cannot be changed; only after a chemical reaction the products have new chemical properties.
Proteins in the membrane, such as enzymes, play a crucial role in facilitating chemical reactions by providing a suitable environment for the reaction to occur. These proteins can catalyze specific reactions and help transport molecules across the membrane to enable cellular processes.
