What enzymes are involved in cell respiration?

Is this why enzymes are involved in cell respiration?

Enzymes are proteins which act as catalysts in reactions such as those involved in cellular respiration. Enzymes increase the chance of a reaction by decreasing the energy needed for it to happen. The reaction does not affect enzymes. Substrats are molecules that bind to enzymes.

How is cell respiration controlled, other than the above? Many cellular respiration enzymes can be controlled by binding regulatory molecules to one or more allosteric locations. Cellular respiration enzymes are controlled by molecules that bind to them. These molecules act as signals and give the enzyme information about its energy state.

This begs the question: Can respiration happen without enzymes?

It is vital that chemical reactions involved with cellular respiration take place at an efficient rate and under the best conditions. Enzymes play a crucial role in this process. Energy of activation without and an enzyme . Each enzyme is responsible for a particular chemical reaction.

What does enzymes mean?

Enzyme is a protein that accelerates a chemical reaction within a living organism. An enzyme is a catalyst for chemical reactions that convert a set of reactants (called substrates), into specific products. Without enzymes, we wouldn't have life as we know.
