Statement 1: Proteins that perform the role of biological catalysts in the body are called receptors.

Statement 2: Proteins that are crucial to a communication system in the body are enzymes.

Both statements are false

The answer for the statements is 3. Both statements are false.

Statement 1: Proteins that perform the role of biological catalysts in the body are called enzymes, not receptors. Enzymes are biological catalysts that speed up chemical reactions in the body. They are not involved in communication between cells.

Statement 2: Proteins that are crucial to a communication system in the body are called ligands, not enzymes. Ligands are molecules that bind to receptors and trigger a cellular response. They are not biological catalysts.

The correct statements should be:

Statement 1: Proteins that perform the role of biological catalysts in the body are called enzymes.

Statement 2: Proteins that are crucial to a communication system in the body are called receptors
