To put it simply, enzymes are proteins that catalyze or speed up the reaction of processes within cells. So when an enzyme attaches to a process, such as metabolism, it can speed up the process. Enzymes regulate those processes by either being "on" or "off", meaning that some energy source such as ATP transfers a phosphate to the enzyme, changing its shape and turning it "on", and allowing it to catalyze the reaction. A good example of this is oxidative phosphorylation, in which the transfer of electrons and protons across the cell membrane at the electron transfer chain site move into a mitochondria, increasing the concentration of protons inside it, and the protons move from this concentrated proton area to the less concentrated area outside the mitochondria through an enzyme called ATP synthetase. This transfer across the membrane creates energy inside the ATP synthetase, like a water-mill, and the synthetase changes ATP into ADP and phosphorylated water, and ADP back into ATP. This facilitates an energy cycle, and thus affects metabolism.

Are enzymes bacterial?
Enzymes are not bacteria themselves, but they are proteins produced by bacteria and other living organisms that act as biological catalysts to accelerate chemical reactions. Enzymes play a crucial role in various biological processes, including metabolism and digestion.
The vitamin that acts as a coenzyme for transaminase enzymes is?
The vitamin that acts as a coenzyme for transaminase enzymes is vitamin B6, also known as pyridoxine. Vitamin B6 plays a crucial role in amino acid metabolism by facilitating the transfer of amino groups between different amino acids.
What are the enzymes of peroxisomes?
Some enzymes found in peroxisomes include catalase, which breaks down hydrogen peroxide, and various oxidases that participate in fatty acid metabolism and help generate hydrogen peroxide. These enzymes play a crucial role in breaking down toxic substances and lipid metabolism within peroxisomes.
Where does drug metabolism occur?
Drug metabolism primarily occurs in the liver, where enzymes break down drugs into metabolites that can be excreted from the body. Other organs, such as the kidneys and intestines, also play a role in drug metabolism to some extent.

What are enzymes What is their role in a cell?
Enzymes are biological catalysts that speed up chemical reactions in cells by lowering their activation energy. They play a crucial role in various cellular processes such as metabolism, digestion, and synthesis of molecules. Without enzymes, these reactions would occur too slowly to sustain life.
What types of enzymes remove hydrogen atoms from its substrate?
Oxidoreductases, particularly dehydrogenases, are enzymes that remove hydrogen atoms from their substrate by catalyzing oxidation-reduction reactions. These enzymes play a crucial role in metabolism by transferring electrons and hydrogen ions between molecules.
Why are enzymes important in metabolism and how do they play a crucial role in the biochemical processes of living organisms?
Enzymes are important in metabolism because they act as catalysts, speeding up chemical reactions in the body. They play a crucial role in biochemical processes by lowering the activation energy needed for reactions to occur, allowing them to happen more efficiently. This helps living organisms break down nutrients, build molecules, and regulate various functions necessary for survival.
How are enzymes created and what is their role in biological processes?
Enzymes are created through a process called protein synthesis in cells. They act as biological catalysts, speeding up chemical reactions in living organisms without being consumed in the process. Enzymes play a crucial role in various biological processes such as digestion, metabolism, and cellular signaling.
Why does the human body require enzymes for proper functioning?
The human body requires enzymes for proper functioning because enzymes are proteins that help speed up chemical reactions in the body. Without enzymes, these reactions would occur too slowly to sustain life. Enzymes play a crucial role in various biological processes, such as digestion, metabolism, and cell repair.
Which best describes the role of enzymes in chemical reactions?
Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by bringing together specific molecules in the correct orientation to promote the reaction. Enzymes are highly specific to their substrates and play a crucial role in regulating metabolism within cells.
What role does copper play in metabolism?
Copper is a necessary co-factor for several enzymes. Most of them have to do with energy production.
