- Vitamin E Supplements: Friend or Foe? Consider the benefits and risks of consuming nutritional supplements. State whether you are for or against consuming nutritional supplements and explain your reasoning. Be sure to cite your sources.Working at cross-purposes? Gluconeogenesis takes place during intense exercise, which seems counterintuitive. Why would an organism synthesize glucose and at the same time use glucose to generate energy?Straight or with a twist? Account for the different structures of glycogen and cellulose.
- Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. Extreme temperatures and pH can cause permanent disruption of the protein primary structure(s) of enzymes that leads to loss of active site shape, loss of binding efficiency and activity.Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. The Michaelis-Menten Constant (Km) of an enzyme is equal to the enzyme concentration at which the initial velocity of the reaction is one half of maximum velocity (Vmax).Why is the reaction rate low at pH7? Be specific and say something about the enzyme structure at the molecular level!
