Question

5 multiple choice 5 points which two factors affect the function of all enzymes? temperature and light intensity ph and carbon dioxide level temperature and ph ph and light intensity 6 multiple choice 5 points when a person cannot break down a sugar like lactose, they are missing the ______ enzyme substrate lipid nucleic acid

Explanation:

Question 5

Enzymes are proteins whose function is affected by environmental conditions. Temperature affects enzyme activity (e.g., optimal temp for human enzymes is ~37°C, too high/low disrupts structure). pH also affects them (each enzyme has an optimal pH, like pepsin in stomach needs acidic pH). Light intensity and carbon dioxide level don't affect all enzymes' function. So the correct factors are temperature and pH.

Lactose is broken down by the enzyme lactase. If a person can't break down lactose, they lack the enzyme (lactase) needed. Substrates are the molecules enzymes act on (lactose is the substrate here). Lipids and nucleic acids are unrelated to lactose breakdown.

Answer:

C. Temperature and pH
