Chains of chemical reactions in living organisms are called?

Metabolic pathways. These pathways involve a series of interconnected chemical reactions that convert molecules into energy or create necessary building blocks for the organism. Each step is catalyzed by specific enzymes to maintain a balance of energy and essential molecules in the organism.


What are pathways that require energy to combine molecules together called?

Pathways that require energy to combine molecules together are called anabolic pathways. These pathways involve the synthesis of complex molecules from simpler building blocks, requiring energy input in the form of ATP.


How its called The ordered sequence of reactions that move store and release energy?

This ordered sequence of reactions is called a metabolic pathway. It involves specific enzymes that catalyze each step in the process of extracting, storing, and releasing energy from molecules such as glucose. Metabolic pathways are essential for sustaining life processes in cells and organisms.


What are energy yielding reactions called?

Energy yielding reactions are called catabolic reactions. These reactions involve breaking down complex molecules into simpler ones, releasing energy in the process. Common examples include glycolysis, the citric acid cycle, and oxidative phosphorylation.


Why catabolic reactions are called convergent reactions?

The various degradative pathways of catabolism are convergent. That is, many hundreds of different proteins, polysaccharides, and lipids are broken down into relatively few catabolic end products. The hundreds of anabolic pathways,however, are divergent. That is, the cell uses relatively few biosynthetic precursor molecules to synthesize a vast number of different proteins, polysaccharides, and lipids.


Complex metabolic reactions proceed in a series of steps called?

Complex metabolic reactions proceed in a series of steps called metabolic pathways. These pathways involve a sequence of enzymatic reactions that transform substrates into products, ultimately contributing to the overall metabolism of an organism. Each step in a metabolic pathway is tightly regulated and often linked to other pathways within the cell.


How do enzymes affect reactions in living cells?

Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.


Chains that contain only 2 glucose molecules are called?

Maltose.


Carbohydrates are chains of what smaller organic molecule?

Carbohydrates are chains of smaller organic molecules called monosaccharides.


Is DNA is a protein?

No. Proteins are made of long chains of amino acids. DNA is made of long chains of only four nucelotides: adenine, thymine, guanine, and cytosine.


What do you call the molecules which make reactions work such as the breakdown of food molecules?

Enzymes are the molecules responsible for catalyzing biochemical reactions, including the breakdown of food molecules. They act as biological catalysts by lowering the activation energy required for these reactions to occur.


All of the chemical reactions of the cell are called?

The chemical reactions of the cell are called metabolism. Metabolism consists of two main types of reactions: catabolic reactions, which break down molecules to release energy, and anabolic reactions, which build molecules using energy. These reactions are essential for the cell to function and maintain life.
