WebWhen oxygen is present, \text {NADH} NADH can pass its electrons into the electron transport chain, regenerating \text {NAD}^+ NAD+ for use in glycolysis. (Added bonus: some \text {ATP} ATP gets made!) When oxygen is absent, cells may use other, simpler pathways to regenerate \text {NAD}^+ NAD+. WebSep 22, 2024 · Oxygen diffuses through cells at a fixed rate, so as clusters get bigger, oxygen can reach the cells in the interior only slowly if at all. Although bigger clusters had a survival advantage within this experiment, the allure of oxygen was so compelling for yeasts that they limited the size of their clusters rather than forsake it.

WebIn unicellular organisms, diffusion across the cell membrane is sufficient for supplying oxygen to the cell (Figure 20.2). Diffusion is a slow, passive transport process. In order for diffusion to be a feasible means of providing oxygen to the cell, the rate of oxygen uptake must match the rate of diffusion across the membrane. WebOxygen is transported to all cells in the body through the following process: Oxygen moves by diffusion from an area of higher concentration inside the lungs to an area of lower …
