Question

the table shows a comparison of muscle cells and blood cells. patterns of gene expression glycolysis enzymes muscle cells on blood cells white on red (immature) on muscle proteins on off off glucagon off off off hemoglobin off off on based on the table, which conclusion can be made? the factors that regulate gene expression for muscle proteins are active in red and white blood cells. the factors that regulate gene expression for glycolysis enzymes are active in muscle and blood cells. the gene that codes for glucagon is active only in muscle cellls. the gene that codes for hemoglobin is absent from blood cells.

Explanation:

Step1: Analyze each option

• For the first option: The table shows that the gene for muscle proteins is off in blood cells, so the factors regulating it are not active in blood cells.
• For the second option: The gene for glycolysis enzymes is on in muscle and blood cells, which implies the factors regulating it are active in these cells.
• For the third option: The gene for glucagon is off in muscle cells, so it's not active only in muscle cells.
• For the fourth option: The gene for hemoglobin is on in (immature) red blood cells, so it's not absent from blood cells.

Answer:

The factors that regulate gene expression for glycolysis enzymes are active in muscle and blood cells.
