A molecule that blocks the activity of carbonic anhydrase would immediately. . .
harina [27]

Answer:

b. cause an increase in blood pH.

Explanation:

Carbonic anhydrases are zinc-containing enzymes that catalyze the reversible reaction of conversion between CO2 and bicarbonates (carbon dioxide hydration and bicarbonate dehydration). The conversion of bicarbonate to CO2 facilitates its entry into the cell. On the other hand, the conversion of CO2 to bicarbonate helps keep the CO2 inside the cell.

This enzyme is important in all living organisms for maintenance of acid-base balance (regulates pH ). For example, carbonic anhydrases lowers pH in the stomach by producing an acid.

g 20. Name two bones connected by an interosseous membrane found in the crus and/or sural region. Which one is the medial bone
slamgirl [31]

Answer:

Tibia and fibula. Tibia (medial bone)

Explanation:

The tibia is the medial bone of the lower leg (it is the second-largest bone next to the femur), whereas the fibula is the lateral bone of the lower leg. The tibia functions to transmit the majority of the force in the lower leg. The tibia articulates at the proximal end with the femur and fibula; where this bone (tibia) articulates at the distal end with the fibula and the talus bone of the ankle. The tibia and fibula are connected via an interosseous membrane, which is a thin sheet of connective tissue that spans the space between two bones.
