What is the advantage of highly folded membranes in a cell?

Webhigher the liquid surface area/culture volume ratio is the better gas exchange is. The data in the Table 2 show comparable SA/volume ratio for Corning and Competitor 2L flasks at both 0.6L and 1.2L volumes, which is consistent with comparable CHO-S viable cell densities in Figure 1. For Corning 3L and 5L WebSep 15, 2024 · September 15, 2024 by Alexander Johnson. Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

WebOct 24, 2015 · Explanation: Alveoli contains many elastic fibres which allows it to expand and recoil according to the volume of air breathed in. When expanding alveoli's surface area is increased and the diffusion rate is faster. Answer link. WebTo calculate SA/vol ratio: divide the surface area by the volume. For example, in the case of an organism with a surface area of 4 meters squared (m 2) and a volume of 2 meters cubed (m 3 ), the SA:Vol ratio is 2. SA/vol ratio = Surface Area Volume = 4 m 2 2 m 3 = 2

WebFor a cell, the ratio of cellular surface area to volume is important because efficient trans-membrane diffusion of molecules (nutrients or wastes) into or out of the cell must occur rapidly enough to sustain cell function.
