Bio 201 Exam 1|Anatomy and Physiology| Review 2024/2025| Complete solution A+ What is the role of electrolytes in maintaining cellular function? Electrolytes help regulate nerve impulses, muscle contractions, hydration, and blood pH. Define embryology, cytology & microscopic anatomy ...Embryology- development before birth, Cytology- cells of the body, Microscopic Anatomy- structures to small to be seen with naked eye How does pH influence enzyme activity in the body? Enzymes hav...

What is cellular metabolism? - Answer-Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life What is the primary function of enzymes, and how are they regulated? - Answer-Enzymes speed up chemical reactions. Most notably, the enzyme is not consumed during the reaction and can be used repeatedly by the cell. Enzymes can also be regulated by a cofactor such that in the absence of the proper cofactor, enzymes are inactive while in its p...

What is kcat? What is a holoenzyme? Correct Answer-Kcat=overall rate of an enzyme, catalytic efficiencies. Holoenzyme (active) is an inactive apoenzyme with non-protein components. (look at the picture) Discuss enzyme-substrate specificity. What is the lock and key vs. induced fit model? Correct Answer-Induced fit: enzyme changes after substrate binds to make it fit more perfectly. Discuss energy implications of enzymes. Does it change the activation energy or free energy of the overal...

Biochemistry Study Guide Questions and Answers Rated A+ What unique feature of enzymes allows them to be highly specific for their substrates? The unique three-dimensional shape of an enzyme allows it to fit only specific substrates, much like a key in a lock. How does the structure of glycogen contribute to its function as an energy reserve? Glycogen's branched structure allows for rapid mobilization of glucose when energy is needed quickly. What is the significance of the ...
