What is the function of an enzyme in a biochemical reaction?

Back

To speed up the rate of the reaction.

Front

What is chitin and what role does it play in insects?

Back

Chitin is a carbohydrate that provides support and protection in the exoskeleton of insects.

Front

What is chitinase and what is its function?

Back

Chitinase is a protein that breaks down chitin for energy to be used by insectivorous bats.

Front

What metric can be used to measure the rate of photosynthesis in plants?

Back

The rate of oxygen production, measured by counting the number of bubbles produced when exposed to different light wavelengths.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged, allowing it to bind to new substrates.

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the complementary DNA strand for the sequence 'C G C A T G'?

Back

G C G T A C.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to increase the speed of chemical reactions without being consumed.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the significance of the enzyme's active site?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.
