      The breakdown of complex molecules, in living organisms, to form simpler ones, together with the release of energy; destructive metabolism.

      I dont understand this part of the definition together with the release of energy

      So anything anti catabolic would be a non breakdown of these molecules used for energy, thus keeping cells from absorbing energy.

      Catabolic responses are responses that include the breakdown of biomolecules, yet what precisely does this mean? When you eat sustenance, you bite it to make it less demanding to swallow, isn’t that so? Catabolic responses are comparative in that they "bite" up biomolecules to make them less demanding to use. Absorption is a catabolic action. Here you start with expansive nourishment molecules, and afterward water is utilized to soften the bonds up those molecules. These littler molecules are then sent off to the cells in your body to take an interest in cellular respiration, which is a process that changes over biochemical vitality to ATP, a high-vitality particle. Cellular respiration is additionally a catabolic process on the grounds that it breaks the little molecules from assimilation into much littler ones as ATP is made. These are both critical processes, on the grounds that ATP is the thing that your cells use to deliver body warmth, move your muscles, and other fundamental substantial capacities.If you need a complete study or written paper about the Catabolic responses and process, the experts from top essay writing services will be a great support for you.

      Catabolism is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy, or used in other anabolic reactions. Catabolism breaks down large molecules (such as polysaccharides, lipids, nucleic acids and proteins) into smaller units (such as monosaccharides, fatty acids, nucleotides, and amino acids, respectively).

      Cells use the monomers released from breaking down polymers to either construct new polymer molecules, or degrade the monomers further to simple waste products, releasing energy. Cellular wastes include lactic acid, acetic acid, carbon dioxide, ammonia, and urea. The creation of these wastes is usually an oxidation process involving a release of chemical free energy, some of which is lost as heat, but the rest of which is used to drive the synthesis of adenosine triphosphate (ATP). This molecule acts as a way for the cell to transfer the energy released by catabolism to the energy-requiring reactions that make up anabolism. (Catabolism is seen as destructive metabolism and anabolism as constructive metabolism). Catabolism therefore provides the chemical energy necessary for the maintenance and growth of cells. Examples of catabolic processes include glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.

      As a biochemist (and not a chemist) I used to believe that the main energy of catabolism comes generally from the breakdown of carbon carbon bonds. And that this energy finally is in ATP. But for instance when I look more precisely at glycolysis the step where carbon carbon bond is cleaved is aldolase (step 5). In my book (Alberts, essential cell biology , third edition) the energy rich phosphate of dihydroxyacetone phosphate and glyceraldehyde 3- phosphate do not look more energetic than the ones of fructose1,6-bisphosphate. The energy seems more in NAD+ in step 6 where a new activated phosphate is created on 1,3-bisphosphoglycerate. But in phosphorylative oxydation I was told that the energy is in NADH which is the electron donor. So from where exactly comes this free energy which ultimately will give ATP and GTP in catabolism ?
