Oxyhemoglobin appears _____ in color; deoxyhemoglobin appears _____.Multiple choice question.darker red; bright redbright red; darker red

To determine the correct answer, let's analyze the properties of oxyhemoglobin and deoxyhemoglobin.

1. Oxyhemoglobin is the form of hemoglobin that is bound to oxygen, and it has a bright red color due to the oxygenation of the iron in the heme group.

2. Deoxyhemoglobin, on the other hand, is hemoglobin that is not bound to oxygen and appears darker red. This occurs because the heme group changes its conformation when it is not oxygenated, resulting in a different interaction with light.

Based on this information, the correct answer to the question is:

Final Answer

Oxyhemoglobin appears bright red in color; deoxyhemoglobin appears darker red.
