First of all living cells use catalysts (more specifically - enzymes), because without them it would need an extremely long period of time for all of the biochemical reactions to finish. Of course, enzymes are not the only thing which may change the speed of the reaction - if the environmental conditions (temperature, pH, pressure and others) are changed the reactions also may start to run faster. But the change of these conditions may kill the organisms or reduce their fitness. For instance, if the temperature becomes higher - yes the reactions would start to run faster. But the nucleic acids and the proteins of the organism are going to denature (their normal folding processes are going to be disrupted), so this eventually would kill or damage the organism (that is what happens when a living tissue is burnt).
To break down sugar and produce useful energy, the cells need many things, but most importantly they need ENZYMES.
Many enzymes are affected by changes in temperature. Cells can regulate the activities of enzymes in many ways. Most cells contain proteins that help turn key enzymes "on" and "off" at critical stages in the life of the cell. Enzymes play essential roles in regulating chemical pathways, making materials that cells need, releasing energy, and transferring info. there ya go ppl....... always there to help ya know (:
Enzymes are made of proteins. They are chains of amino acids that join together to perform a specific function. Enzymes are responsible for the chemical reactions that occur in a cell. Cells need enzymes to live. Without the enzyme an organ in the body cannot function properly. Prokaryotic and Eukaryotic cells also use enzymes for the reactions that take place in their cell.
cells need membranes.A cell travels throughout the blood stream. There are 2 types of cells: animal and plant cells. hope i hav answered your question
Cells do not need to continuously manufacture large amounts of each enzyme since enzymes can be used over and over. Since they can be used in multiple reactions and in small amounts, enzymes don't have to be constantly made by the body.
Enzymes are protein in cells that lower the energy of a reaction. Without enzymes, reactions would need more energy than the body can make. This would cause death of the cells.
Viruses need living cells for reproduction .
All living things need cells to live
Living things need cells to live and survive.Without cells,they cannot live. Plants and animals are some examples of living things who have cells in their body.

need? it's all relative. I'm sure that the very first cells lacked all enzymes.Your cells need them to keep up with the competition.

yeah.
None all living things need cells to live the cells have all things needed for life so if something doesn't have cells it is not alive.
All living things are organisms. There is no such thing as a living cell that is not an organism.
