Agroup of students has performed an experiment to study the ideal temperature for the maximum activity of biological enzymes. enzymes are specific to their environment; in other words, they work best at a specific ph and specific temperature. which graph represents optimum enzyme activity at approximately 37 degrees celsius?
refer to figures below.

Answer;

The first graph represents such an enzyme.

Explanation;

This is because the enzyme demonstrates greatest activity at approximately 37 °C but then the activity starts to decrease due to the denaturing of the enzyme.

As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. The graph shows the typical change in an enzyme's activity with increasing temperature. The enzyme activity gradually increases with temperature up to around 37 ºC, or body temperature. Then the activity decreases above 37  ºC, because above this temperature the enzymes will denatured.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
