Answer:
B
Explanation:
This H+ ion gradient is referred to as a proton motive force. It is created using energy from the Krebs cycle in the matrix of the mitochondria. As electrons are passed from one protein complex to another, reducing molecules such as NADH and FADH2, the protons are pumped to the intermembrane space of the mitochondria. ATP synthase uses this potential to generate ATP as the H+ ions move downgradient (back to the matrix) through channels in the protein enzyme.
The answer is All of these for m<span>utagens cause changes (mutations) in the genetic material of cells. Teratogens cause irreversible, deleterious structural malformations in fetuses. Carcinogens cause cancerous tumors with a characteristically crablike appearance.</span>
How does molecular size affect to the permeability
of the membrane to that molecules?
So you will try to find out how many
molecules of each kind pass through the membrane per time unit. If molecules
pass faster, it’s highly permeable to that material. Some molecules may not
pass at all, so then it’s not permeable to that material. Then you can put the materials
in order from the lowest to the highest permeability. You can also try to find
a mathematical formula that shows how permeability increases or decreases as size
increases (usually it decreases). Exel is usually helpful to find that formula:
you can make a plot and see if it is linear, exponential, potential, etc. There
are other softwares with a larger variety of graph options tan Excel.
