Some bacteria live in hot springs. Their cells contain enzymes that function best at temperatures of 70 °C or higher. At the temperature of 50 °C, how will the enzymes in these bacterial cells most likely be affected?

Show how to bring about the following chemical transformation. This transformation might require one or several steps. CH3 O O CH3 OH CH3 OH CH3 OH K CH3 OH CH3 OH H3PO4 heat H3PO4 heat H₂O/H₂SO4 H3PO4 heat CH3 CH3 H₂O/H₂SO4 H₂ Pt CH3 H3PO4 heat CH₂ H₂O/H₂SO4 CH3 CH3 CH3 CH3

Human lysozyme is an enzyme active in lysosomes.  At approximately what pH would you expect this enzyme to display maximal activity?   Question options:   enzyme activity should be reasonably similar at all of these pH values   9   7   5   11

please explain

What's the difference between a calorie, an ATP molecule, and a GTP molecule? How does GTP become ATP? Also, explain how ATP is made. A clear explanation and graphic are required.

Please, please I do not understand this question for Biochemistry. Can you help me? Steps leading to the correct answer would be helpful!

Can you please solve the following question, both parts please.

You are studying a biochemical pathway that requires ATP as an energy source. To your dismay, the reactions soon stop, partly because the ATP is rapidly used up and partly because an excess of ADP builds up and inhibits the enzymes involved. You are about to give up when the following table from a biochemistry textbook catches your eye. A. ذن فه B. Substrates C. Creatine + ATP ATP + H₂O Pyrophosphate + H₂O Glucose-6-phosphate + H₂O Enzyme A Enzyme B Enzyme C Enzyme D Products Creatine-phosphate + ADP Which of the following reagents is/are most likely to revitalize your reaction? a vast excess of ATP glucose 6-phosphate and enzyme D creatine phosphate and enzyme A D. pyrophosphate ADP + Phosphate 2 Phosphate Glucose + Phosphate AG (kJ/mol) +3 -7.3 -7.0 -3.3

Lysozyme catalyzes a "bi-bi" reaction. List, in order, the reactants that bind and the products that are released during a lysozyme-catalyzed reaction cycle.

Fill in the blanks and answer the question:   A. The enzyme ATCase (aspartate transcarbamoylase) uses _________________control to regulate its activity. The molecule ATP is an allosteric _____________ of ATCase and because it is a molecule different from the substrate of this enzyme it produces an _________________ effect in the enzyme’s activity.   B. Is it appropriate to study the enzymatic activity of ATCase with the Michaelis Menten approximation? Justify your answer.
