- The enzymes involved in respiration, photosynthesis and protein synthesis work inside cells. Other enzymes are produced by specialised cells and released from them; the digestive enzymes are like this.They pass out into the gut, where they catalyse the breakdown of food molecules.verall, this means that: 1  Amylase catalyses the breakdown of starch into sugars in the mouth and small intestine. 2  Proteases catalyse the breakdown of proteins into amino acids in the stomach and small intestine. 3  Lipases catalyse the breakdown of fats and oils into fatty acids and glycerol in the small intestine.

The Endomembrane System and Proteins When food is eaten or absorbed by the cell, the lysosome releases its enzymes to break down complex molecules including sugars and proteins into usable energy needed by the cell to survive. If no food is provided, the lysosome's enzymes digest other organelles within the cell in order to obtain the necessary nutrients. In addition to their role as the digestive component and organelle-recycling facility of animal cells, lysosomes are considered to be parts of the endomembrane system.

Basic Mechanisms of Replication One, a 3 to 5 exonuclease, is intimately involved in the accuracy of replication. Nucleases are enzymes that catalyze the breakdown of DNA or RNA into smaller fragments and/or nucleotides. An exonuclease catalyzes cleavage of nucleotides from the end of a DNA or RNA polymer.he enzyme primase catalyzes the synthesis of the primers from which DNA polymerases can begin synthesis (Figure 5.21). Primers are short oligonucleotides, ranging from 6 to 60 nucleotides long. They can be made of ribonucleotides or a mixture of deoxyribonucleotides and ribonucleotides.

- Structure of Cellulose. Cellulose is a polymer of glucose which is digested by a variety of enzymes. In simple terms, the enzymes may either cleave glucose dimers from the end of the polymer (exocellulase), or fragment the cellulose polymer into smaller molecules by internal digestion of the polymer (endocellulase).n each case, a glucose dimer is absorbed and this is cleaved within the cytoplasm. Cellulases are especially common in soil and plant inhabiting fungi. Many fungi in the Ascomycotina and Basidiomycotina are able to digest cellulose. The necessary enzymes are less common in members of the Zygomycotina.

What is the role of RNA polymerase in protein synthesis? Apr 7, 2015. RNA polymerase enzymes are essential to life and are found in all organisms and many viruses. In chemical terms, RNAP is a nucleotidyl transferase that polymerizes ribonucleotides at the 3' end of an RNA transcript. RNAP can initiate transcription at specific DNA sequences known as promoters.

Biochemistry/Proteins/Introduction Specifically, enzymes either make or break chemical bonds. Protein enzymes should not be confused with RNA-based enzymes (also called ribozymes), a group of macromolecules that perform functions similar to protein enzymes. Further, most of the scaffolding that holds cells and organelles together is made of proteins.hey are, on the other hand, a fundamental nitrogen and amino acid reserve for many organisms. Proteins do not directly function as a membrane in most organisms, except viruses; however, they are often important components of these structures, lending both stability and structural support.

What Role Do Vitamins Play in Enzyme Activity? What Role Do Vitamins Play in Enzyme Activity? By Scott Auerbach; Updated April 25, 2017 Vitamins are essential compounds that must be acquired through the diet because the body can't synthesize them. One of the reasons vitamins are needed is because they play an indirect role in catalysis, in which enzymes speed up chemical reactions. However, most vitamins can't help enzymes on their own. In order to participate in catalytic reactions, most vitamins have to change into coenzymes that are small co-pilot molecules that pair up with enzymes.

What are the monomers that make enzymes? Best Answer: Amino Acids are the monomers that make up protein.... and enzymes are a type of protein. (i.e. the peptide chain is the polymer made of amino acid monomers). There may be a-helixes and b-sheets formed (secondary structure). This chain then folds (into tertiary).

Explain the significance and importance of hydrolysis and condensation reactions in bioligical systems? Making and breaking of polymers: Dehydration synthesis: is an anabolic process by which two molecules are chemically bonded through the use of enzymes and a loss of water. glucose + glucose + enzyme = maltose + water + enzyme. Hydrolysis: is a catabolic process by which the bond between monomers are broken by the enzyme and the addition of water. sucrose + water + enzyme = glucose + fructose + enzyme.

Role of enzymes in metabolism Role of enzymes in metabolism Some enzymes help to break down large nutrient molecules, such as proteins, fats, and carbohydrates, into smaller molecules. This process occurs during the digestion of foodstuffs in the stomach and intestines of animals.

Polysaccharides In fact, messenger RNA is what makes possible proteins, peptides, and enzymes. Enzymes help do the chemistry inside living organisms and peptides make up some of the more interesting structural components of skin, hair, and even the horns of rhinos. Other natural polymers include polysaccharides (sugar polymers) and polypeptides like silk, keratin, and hair. Natural rubber is, naturally a natural polymer also, made from just carbon and hydrogen. Let's look at each of the main families of natural polymers closely.

- Describe the role of enzymes in chemical reactions. Ans: Enzymes facilitate the chemical reaction without being changed themselves. For example, an enzyme may bring together two molecules that bond with each other, or break the bond of two other molecules. In either case, the enzyme accelerates the reaction.

Monomers and Polymers Chemistry The word monomer comes from mono- (one) and -mer (part). Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization. Sometimes polymers are made from bound groups of monomer subunits (up to a few dozen monomers) called oligomers.
