Which of the following best describes the pH of the endosomal interior? a.) The interior of an endosome generally has a higher pH than cytoplasm. b.) The interior of an endosome generally had a lower pH than cytoplasm. c.) The interior of an endosome generally had a pH similar to cytoplasm.arrow_forwardDraw and label a cell lipid bilayer and diagram how the following transport processes take place: passive diffusion of oxygen into the cell, facilitated diffusion of potassium into the cell, active transport of sucrose into the cell. Using different symbols (circles for oxygen, squares for sucrose, and triangles for potassium ions), show the relative concentrations (gradients) of these substances on the inside and outside of the cell. For example, to show that oxygen enters the cell by going “down” its gradient, you would draw more circles on the outside of the cell than inside the cell. Be sure to show and label membrane proteins when appropriate, and show the electric membrane potential using “+”s (pluses) on one side and “-”s (minuses) on the other side of the membrane. Also show the proton pump which uses ATP as a source of energy.arrow_forward

Which of the following describes the most likely subcellular component and related process responsible for the development of Gaucher disease? A B с D Lysosomes contain insufficient amounts of enzymes necessary for the metabolism of lipids. The Golgi complex produces vesicles with highly permeable membranes that cannot ef- fectively regulate the movement of particles. Mitochondria are not producing a sufficient amount of ATP required for the digestion of lipids. The rough endoplasmic reticulum contains an unusually high number of ribosomes, re- sulting in an overproduction of digestive enzymes.arrow_forward
