Question

• label the diagram below with the following terms: enzyme/substrate complex, substrate, enzyme, products
• if you see a word that ends in -ase, it is probably a(n)
• if you see a word that ends in -ose, it is probably a(n)
• the area in which a substrate molecule fits into an enzyme is known as the
• a cell that has 50 chromosomes divided by mitosis, how many chromosomes will each of its daughters cells contain? identical or non-identical? how many cells are made?
• list three purposes of mitosis in eukaryotic organisms.
• a cell that has 20 chromosomes divided by meiosis, how many chromosomes will each of its daughters cells contain? identify or non-identical? how many cells are made?

Explanation:

1. Enzyme-Substrate Diagram: Enzymes (B, C, E) are the stable, reusable structures; the substrate (A) binds to the enzyme to form the enzyme/substrate complex (D), and the reaction produces products (F).
2. -ase Suffix: This suffix universally denotes enzymes (biological catalysts).
3. -ose Suffix: This suffix is characteristic of sugar molecules (carbohydrates).
4. Active Site: This is the specific region on an enzyme where the substrate binds.
5. Mitosis: This process produces genetically identical daughter cells with the same chromosome number as the parent, creating 2 cells total, used for growth, repair, and asexual reproduction.
6. Meiosis: This reduction division produces 4 genetically non-identical daughter cells, each with half the parent cell's chromosome number, for sexual reproduction.

Answer:

A: Substrate
B: Enzyme
C: Enzyme
D: Enzyme/substrate complex
E: Enzyme
F: Products
