The ability to maintain concentration gradients and sometimes move materials against them is vital to cell health and maintenance. Thanks to membrane barriers and transport proteins, the cell can ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a ...

Speaker one: Osmosis is the diffusion of water molecules across a semi-permeable membrane, from a higher water concentration, to a lower water concentration. Speaker two: Water uptake in plants ...

The water concentration can be thought of as the proportion of a solution that is water. Solutions with a high concentration of solute molecules, such as sugars or salts, have a low concentration ...

Organizationally, each of the 6 graduate programs in Biological Sciences allows focused training in a student’s choice of one of two concentrations: Molecular Biology and Genetics (MBG) or Cell and ...
