While every level of a protein's structure is important to the function of that protein,
which level of structure is most important to FUNCTION OF THE ENZYMES AND
WHY?
Streptokinase is an enzyme produced by Streptococci bacteria and is used to digest fibrin clots. It is therefore very effective at eliminating blood clots that cause heart attacks and strokes. Why does a physician not worry that injecting streptokinase will also destroy healthy tissue in their patients? – this answer should discuss the specificity of enzymes for their substrates, defined by the shape of the active site.
Why is concentration of an enzyme in a cell is much lower than that of its substrate?

- Find an enzyme that is used by humans for some industrial or useful process (apart from its original purpose; e.g. food production, textiles, agriculture, clinical diagnosis, medical treatment, biofuel production, material polymerization, etc.). How do we obtain or harvest the enzyme? What reaction(s) does it catalyze, and how is this useful for its industrial purpose? 200 words onlyarrow_forwardEnzymes are proteins that increase the rate of chemical reactions by lowering the energy activation required to facilitate the process. Explain the generalized and sequential enzyme mechanism of action (hint: from substrates to products).arrow_forwardThe ____ sites of an enzyme can be used to regulate enzyme activity within a cell, and thereby control their metabolism.arrow_forward
- The active site of an enzyme is a small portion of the enzyme molecule. What is the function of the rest of the huge molecule?arrow_forwardMost efficient enzyme isarrow_forwardThe active (catalytic) site of an enzyme contains the side chains of amino acid residues that areconserved because they participate in the protein’s catalytic activity. The bulk of the enzyme,however, is not part of the active site. A substantial amount of energy is required to synthesizeenzymes. Why are these molecules so large?arrow_forward
- For effective metabolic pathway regulation, a(an) ______ binds to the enzyme catalyzing the first committed step in a metabolic pathway.arrow_forwardA very special property of enzymes is Feedback inhibition. What is feedback inhibition? Draw a hypothetical cyclic pathway where in there are 7 reactions to show feedback inhibition.arrow_forwardDigestive Enzymes Digestive enzymes are protein-based biological catalysts that have important roles in our lives. They help remove stains from our clothing, turn milk into cheese, and are responsible for turning our dinner into usable fuel for our bodies. Enzymes, however, do not work well universally. Some are meant to work at high temperatures, others at low temperatures. They may work best in acidic conditions or neutral conditions. In this activity, the optimal conditions for two different digestive enzymes will be considered. Lipase is made in the pancreas and breaks down lipids in the small intestine. Pepsin breaks down proteins in the stomach. triglycerides polypeptides Enzymes and Cellular Regulation Rate of reaction a. pepsin b. lipase lipase pepsin glycerol + fatty acids PH small peptides + amino acids Effect of pH on Enzyme Activity 8 10 12 14 Pepsin (stomach) -Lipase 1.

- Often, an enzyme requires a cofactor or prosthetic group in its active site in order to be an efficient catalyst. Many such cofactors are synthesized by plants and obtained in the diet as vitamins. Find a description in your text of a particular B vitamin. Give its name and describe its biological function in terms of the name(s) and function(s) of the enzyme(s) that require it.arrow_forwardTrue or false Enzymes are not only proteinaceous in nature, but some RNA molecules such as ribozymes can also be enzymes.
