Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...

Question 9 Diffusion is an important process at the micro and nano scale and different devices may be designed to minimize it, compensate for it, or take advantage of it. (a) Explain what is meant by the term diffusion and describe how it occurs, illustrating your answer with references to each of the following: (i) a hole in a semiconductor such as silicon (ii) a protein molecule within a living cell. (6 marks) Explain why diffusion could be a particular...

During high-intensity exercise such as sprinting or lifting a
very heavy weight, energy is provided to cells by the phosphogen
system (or ATP-PC system), which only works for a few seconds. If
the diffusion constant of ATP is 3 ×10−10 m2 s-1, how far could
this molecule diffuse in 8.3 seconds?

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

8. Consider how the heavy elements that make up planets like the earth are formed. Which of the following is most likely to be true about the origin of Earth? Earth arose around a very ancient star (our sun) that had had plenty of time to synthesize heavy elements. Earth arose in a region of our galaxy where few earlier stars formed so that the hydrogen fuel for our sun was abundant. Earth arose in a region that was very...
