What is the chemical reaction for CO 2 dissolving in H 2 O?

H 2 O + CO 2  H 2 CO 3  HCO H + What is the chemical reaction for CO 2 dissolving in H 2 O?

In what part of the body would the chemical reaction go to the left? In what part of the body would the chemical reaction go to the right?

Lungs/Alveoli: TO THE LEFT!!! Body/Brain tissues: TO THE RIGHT!!!

What is hemoglobin bound to O2 called? What is hemoglobin bound to nothing called? What is Hemoglobin bound to CO2 called? What is the symbol for hemoglobin?

What is hemoglobin bound to O2 called? Oxyhemoglobin What is hemoglobin bound to nothing called? Deoxyhemoglobin What is Hemoglobin bound to CO2 called? Carbaminohemoglobin What is the symbol for hemoglobin? Hb

Where is PO 2 high and PCO 2 low? Why?

The Tissues. The capillaries have plenty of O 2. Picked up at the lungs. The cells have used up their O 2 in the mitochondria making ATP. Capillaries lost their CO 2 at the lungs. Therefore little CO 2 in the blood at this point. Where is PO 2 high and PCO 2 low? Why?

Name four components of Hemoglobin. How many each?

1. Alpha globin ~ 2x 2. Beta globin ~ 2x 3. Heme ~ 4x 4. Iron ~ 4x Name four components of Hemoglobin. How many each?
