Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions in living organisms.

Front

What happens to an enzyme's active site when temperature is too high?

Back

The active site can change shape, leading to denaturation and loss of function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its shape due to extreme temperature or pH, rendering it inactive.

Front

Give an example of mutualism.

Clownfish and sea anemones: clownfish get protection, and sea anemones get food scraps.

Back

Barnacles attaching to whales: barnacles benefit by getting a place to live, while whales are not affected.

Front

Give an example of parasitism.

Back

Mistletoe on oak trees: mistletoe extracts nutrients, harming the oak.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.
