Analyze the effect of increased CO2 diffusion from muscle tissues into red blood cells on hemoglobin's oxygen release.

Increased CO2 diffusion enhances proton production, decreasing hemoglobin's oxygen affinity and promoting oxygen release.

Increased CO2 diffusion enhances oxygen production, decreasing hemoglobin's oxygen affinity and promoting oxygen release.

Increased CO2 diffusion reduces proton production, increasing hemoglobin's oxygen affinity and inhibiting oxygen release.

Increased CO2 diffusion has no effect on hemoglobin's oxygen release.
