value: 10
most carbondioide is transported as ______.
\ta. carboaminohemoglobin
\tb. bicarbonate
\tc. free carbon dioxide
\td. hemoglobin
\te. nitrate
\tf. carbohydrate

value: 10
increasing temperature ______ oxygen bining to hemoglobin.
\ta. increases
\tb. decreases

value: 10
the hormone from the kidneys that functions to increase the production of red blood cells is ______.
\ta. erythrohemocytoblast
\tb. erythropoietin

Explanation:

1. Hemoglobin is a protein specialized for oxygen transport, located in red blood cells (erythrocytes).
2. Most CO₂ in blood is converted to bicarbonate ions ($HCO_3^-$) via carbonic anhydrase, the primary transport form.
3. Higher temperatures shift the oxygen-hemoglobin dissociation curve right, reducing oxygen binding (Bohr effect).
4. The kidney hormone erythropoietin stimulates red blood cell production in bone marrow.

Answer:

1. c. Red Blood cells
2. b. Bicarbonate
3. b. decreases
4. b. Erythropoietin
