Front

What is the role of enzymes in cellular reactions?

Back

Enzymes are necessary because they speed up reactions that would otherwise be too slow to meet the needs of the cell.

Front

What is the complementary DNA sequence for CTG-CAT?

Back

The complementary DNA sequence is GAC-GTA, as Cytosine pairs with Guanine and Adenine pairs with Thymine.

Front

What happens to the active site of an enzyme at high temperatures?

Back

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

Front

What is the function of parts X and Y in a cell?

Back

Parts X and Y work together to provide structural support to the cell.

Front

How can you distinguish between eukaryotic and prokaryotic cells?

Back

Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not.

Front

What is the function of lactase in the body?

Back

Lactase is an enzyme that breaks down lactose, the sugar found in milk.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate DNA replication and transcription.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within eukaryotic cells, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it decreases due to denaturation.

Front

What is the primary structure of proteins?

Back

The primary structure of proteins is the sequence of amino acids linked by peptide bonds.
