answer both please

What is NOT true about the effect of temperature on enzymes? at very high temperatures most enzymes are denatured enzymes are more sensitive than non-catalyzed reactions to temperature changes the Q10 for enzyme reactions is similar to that for chemical reactions. enzymes are subject to inhibition at higher temperatures enzyme reactions rates can increase markedly as the temperature is raised Question 35 What is true about NAD+/NADH? can only act as a reducing agent can only act as an oxidizing agent the ribose is directly involved in oxidation reactions does not contain a vitamin component contains ribose, phosphate and adenine What is NOT true about the effect of temperature on enzymes? at very high temperatures most enzymes are denatured enzymes are more sensitive than non-catalyzed reactions to temperature changes the Q10 for enzyme reactions is similar to that for chemical reactions. enzymes are subject to inhibition at higher temperatures enzyme reactions rates can increase markedly as the temperature is raised Question 35 What is true about NAD+/NADH? can only act as a reducing agent can only act as an oxidizing agent the ribose is directly involved in oxidation reactions does not contain a vitamin component contains ribose, phosphate and adenine
