Biochemical reactions are chemical reactions that take place inside the cells of organisms.
Additionally, how does chemical change occur in your body?
Our bodies do this by creating chemical reactions. A chemical reaction changes one set of chemicals into another. A series of chemical reactions turns the food we eat into energy that can be used by our cells. Other series of reactions spend that energy by building cells, growing and exercising.
Subsequently, what is biochemical reactions in the body?
Definition. A biochemical reaction is the transformation of one molecule to a different molecule inside a cell. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells.
What is the site for biochemical reactions in a cell?
They include ribosomes, lysosomes and mitochondria, where many of the reactions that produce energy take place. The rest of the cell is occupied by a gel-like fluid, called the cytosol, that contains ions and other substances and that surrounds the other internal elements.
What must be present for every biochemical reaction to occur?
Chemical reactions (including biochemical reactions) can occur when reactants collide with sufficient energy to react. The amount of energy that is sufficient for a particular chemical reaction to occur is called the activation energy.
Which biochemical process occurs in the mitochondria?
The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).
