True of false:

1. The Bohr effect explains the manner in which pH changes the binding affinity of hemoglobin for O2.

i think this is true


2. Hemoglobin binding affinity increases as Po2 increases.

im not sure about this


3. O2 will passively diffuse and bind with hemoglobin that is less than 1mm from the surface of a blood sample.

i think this is false


4. An oximeter is a device that is used to determine percent CO2 saturation of blood.

i think this is false


5. A rightward shift in the O2-dissociation curve means that hemoglobin is more likely to bind with O2.

im not sure about this

please help!
