The existence of carbohydrates in leaves can be sampled by the Iodine test. When chlorophyll is removed from the leaf by boiling it in alcohol and then placing two drops of iodine solution it turns blue in color which indicates the presence of starch.

Marina CMI [18]

The following factors will decrease the amount of oxygen discharged by hemoglobin to peripheral tissues.

A) decreased temperature

B) increased pH

C) decreased amounts of DPG

D) increased tissue PO2

How oxygen is being transported?

About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.
