Front

What happens to the shape of an enzyme's active site when exposed to high temperatures?

Back

The shape of the enzyme's active site changes, which can decrease its activity.

Front

What is the role of structural components in a cell?

Back

They provide structural support to the cell.

Front

How do enzymes affect the breakdown of sucrose in the body?

Back

Enzymes increase the rate at which sucrose breaks down into glucose and fructose.

Front

What is the significance of surface area in mitochondria?

Back

More surface area in mitochondria allows for more energy production.

Front

What is the complementary DNA sequence for CTG-CAT?

Back

GAC-GTA, because in DNA, Cytosine pairs with Guanine and Adenine pairs with Thymine.

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in the body.

Front

What is the function of lactase?

Back

Lactase is an enzyme that breaks down lactose into glucose and galactose.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate, up to a point.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like temperature or pH.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are the powerhouses of the cell, producing energy through cellular respiration.
