Question

the diagram below represents the effect of ph on the activity of a digestive enzyme. effect of ph on enzyme activity. enzyme activity. ph. pepsin is a digestive enzyme found in the stomach. which statement describes why the enzyme activity changes when the ph increases? enzyme activity decreases because there is an increase in h+ ions. enzyme activity decreases because there is a decrease in oh - ions. enzyme activity decreases because there is less substrate available. enzyme activity decreases because the enzyme unfolds.

Explanation:

Enzymes are proteins and their activity is affected by pH. High pH can cause the enzyme (like pepsin) to denature, which means it unfolds and loses its functional shape, reducing its activity.

Answer:

Enzyme activity decreases because the enzyme unfolds.
