Question

Consider individuals who have SCD or SCT. Which statement does NOT describe how the structure of sickled cells affect their function.

a. Sickle-shaped red blood cells have stretched out out cell membranes that leak nutrients.
b. Sickle-shaped red blood cells are not able to efficiently deliver oxygen that is essential to body functions.
c. The c-shape of sickle cells allows for adequate nutrient absorption and appropriate levels of oxygen to be circulated throughout the body.
d. The c-shape of sickle-cells results in the clumping of red blood cells creating blockages

Answer 1

The statement that does NOT correctly describe the effect of sickled cells is that the c-shaped cells allow for adequate nutrient absorption and appropriate oxygen circulation. This is incorrect as sickle-shaped cells disrupt blood flow and oxygen delivery. Therefore correct option is C

Step-by-step explanation:

Out of the statements provided about the individuals who have Sickle Cell Disease (SCD) or Sickle Cell Trait (SCT), the statement that does NOT describe how the structure of sickled cells affect their function is: "c. The c-shape of sickle cells allows for adequate nutrient absorption and appropriate levels of oxygen to be circulated throughout the body." This statement is incorrect because the abnormal crescent shape of sickled cells does not allow for adequate nutrient absorption, nor does it enable proper oxygen circulation. Instead, these sickle-shaped red blood cells deliver less oxygen to tissues, can become lodged in capillaries, and are associated with a variety of serious complications including pain, organ damage, and strokes.
