Question

Why arc cooked pineapples useful to make gelatin dessert but fresh pineapples are not? A. The heat reacts with the gelatin B. The heat melts the gelatin C. The heat denatures the pineapple proteases D. The heat breaks all the covalent bonds The nickel coin in the enzyme activity we did in class was an example of a(n) inhibitor. A. uncompetitive B. competitive C. noncompetitive D. irreversible At constant enzyme concentration, an increase in substrate concentration always results in: A. the same increase in rate of reaction B. a decrease in rate of reaction C. some increase in rate of reaction D. no change in rate of reaction

Explanation / Answer

Q48

The heat denatures proteases, which are helpful in "gelatin" material, choose C

Q50

increasin substrate oncentration must increase the rate of reaction (if enzumes are not saturated)

NOTE: for Q49, consider adding more informtion on nickel coin lab practice
