The movement of water across a concentration gradient. Certain molecules cross the plasma membrane through the process of active transport. Which of the following is generally true within the human body? The amino acids that are in contact with the First, it is happening thanks to the concentration gradient. purple dye is greater on side B. What is the difference between movement of a single molecule versus movement of a population of identical molecules? hypotonic lysed What are the molar concentrations of Cd2+\mathrm{Cd}^{2+}Cd2+ and S2\mathrm{S}^{2-}S2 in a saturated CdS solution if the KspK_{\text {sp }}Ksp of CdS\mathrm{CdS}CdS is 1.01024? An enzyme's function is most dependent on its _____________. molecules down their conentration gradent; aSide with lower concentration of molecules; *disorder has decreased To log in and use all the features of Khan Academy, please enable JavaScript in your browser. antibody, Part B BioFlix Activity: Membrane Transport -- Facilitated Diffusion. endocytosis A form of passive transport. Membrane Transport -- Active Transport ANSWER: Hint 3. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. Is kinetic energy conserved in an elastic collision? proteins. BioFlix Activity: Membrane Transport -- Active Transport Certain molecules cross the plasma membrane through the process of active transport. -The prefix "endo-" means "inward. Required fields are marked *. BioFlix Activity: Membrane Transport-Facilitated Diffusion Drag the labels to their Side with higher of Answer Pic 1 Part A. Fecilitated Diffusion. Charged ions and polar molecules such as sugars and amino acids cannot diffuse directly through the lipid bilayer because they are much more stable Membrane proteins help move molecules across the membrane. is present.
