Thus, the transport of biological substances may occur in intracellular and extracellular fluids. Etymology: The term transport came from Middle English, Old French transporter, meaning “to carry” or “convey across”. It is derived from the Latin transporto, from trans-, meaning “across” ...
Membranes are lipid bilayers exhibiting selective permeability, meaning that they are permeable to some substances and not to others. Membrane transport is mediated by membrane-transport proteins. Latest Research and Reviews Predicting cardiac frequencies in mammals Rui D. M. Travasso Clint A. Penick...
Answer to: Explain the meaning of active transport as used in biology. By signing up, you'll get thousands of step-by-step solutions to your...
ATP) is not required as it is in active transport. Rather, passive transport utilizes kinetic and natural energy to drive the movement. Conversely, in active transport, the movement is uphill, meaning they move from an area where they are less in number to an area where they already are ...
Understanding sperm transport, and especially the key factors which distinguish the “privileged” sperm subpopulation from all the others, is extremely important in many different aspects of reproductive biology. From an evolutionary or genetic viewpoint we might ask whether the female reproductive tract...
Additionally, the overexpression of LuxR resulted in rapid consumption of glucose in Gluconacetobacter xylinus (Zhang et al., 2021), meaning that AHL-QS could promote sugar uptake in the referred bacteria. Conversely, under nutrient deficiency conditions, AHL-QS inhibited sugar uptake in B. glumae...

Briefly explain the meaning of endocytosis and exocytosis as used in biology.What are the two types of facilitated diffusion and what is an example of each?What term describes the movement across a membrane which requires no energy?Facilitated diffusion is a form of cell transport that?
The stoichiometry of the /exchange resulted close to one in both directions. The relative kinetics supports the assumption that the process is mediated by a bound protein. The results may rationalize the circumstance that is taken up by myocardium against a concentration gradient. The meaning of ...
