Witryna5 cze 2024 · The anatomy of specific tissues or organs such as in seeds, fruits and roots may limit oxygen diffusion, leading to hypoxia [55,56,57]. In bulky organs, the oxygen concentration can be very low in the inner part of the organ [ 58 ], thus limiting oxygen for respiration. Witryna9 gru 2024 · FIGURE 4. Proposed mechanisms of oxygen sensing in the carotid body. According to the “Membrane Hypothesis,” oxygen-sensitive potassium channels close within type I cells of the carotid body in response to hypoxia. This leads to membrane depolarization and the opening of voltage-gated calcium channels.
