What are differentiations of the cell membrane?
What is the relation between concentration gradient and active and passive transport?
What are the three main types of passive transport?
What is the energy source used in active transport through biological membranes?
What is the difference between simple and facilitated diffusion? Facilitated by which type of molecule does the term “facilitated” mean?
What is the difference between chromatin and chromosome?
How does the intensity of facilitated diffusion vary in relation to the concentration of the moved substance? What is the limiting factor?
How does the intensity of simple diffusion vary in relation to the concentration gradient of the moved substance?
Without saturation of transport proteins and under same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion?
What are the molecular facts that support the hypothesis? To which other cellular organelles the hypothesis can also be applied?
What is the endosymbiotic hypothesis about the origin of mitochondria?
Where in the cell can ribosomes be found?
Of what substance the plant cell wall is made? Is that substance a polymer made of which monomer?
What are the substances that constitute the chromatin?
What is the main biological function of ribosomes?
