What Are Enzymes? Video/Questions

What is the primary role of enzymes in the body?

• They serve as raw materials for building tissues.

• They are protein worker bees that perform tasks.

• They act as a genetic blueprint for cells.

• They function as copy machines for cellular processes.

How do enzymes process food in the body?

• They only break down food into smaller particles.

• They only build up new tissue from smaller particles.

• They both break down food into smaller particles and build up new tissue.

• They convert food directly into genetic material.

What critical function do enzymes perform regarding the genetic code within cells?

• They create new DNA strands.

• They interpret the RNA instructions.

• They scan for and correct errors in the genetic code.

• They transport genetic material out of the cell.

What is a unique characteristic of enzymes regarding their involvement in chemical reactions?

• They are consumed and destroyed after each reaction.

• They are permanently altered after catalyzing a reaction.

• They recycle themselves and are not used up in the reaction.

• They require constant replenishment from external sources.

How do most drugs affect enzymes in the body?

• They enhance enzyme activity.

• They act as enzyme inhibitors.

• They provide additional co-factors for enzymes.

• They help enzymes to recycle more efficiently.

What environmental factor is crucial for activating certain enzymes, such as the protein enzyme in the stomach?

• Temperature

• Hormone levels

• pH changes

• Presence of inhibitors

What is a potential long-term consequence of consuming too many cooked foods?

• Increased enzyme production in the body.

• Enhanced nutrient absorption.

• Depletion of enzyme reserves, leading to degenerative disorders.

• Improved digestive efficiency.
