A correct distinction between facilitated diffusion and active transport of a substance across a biological membrane is that . . . A. active transport requires conformational changes in the transport protein associated with the transport process, and facillitated diffusion does not. B. active transport requires integral membrane protein to carry out the transport, and facillitated diffusion does not. C. facilitated diffusion depends on an existing energy gradient acting on the transported substance, while active transport makes such a gradient. D....

Magnesium ions move out of a cell through a transmembrane protein down (i.e. with) their concentration gradient. The energy harvested from this movement of magnesium ions is used to move sodium ions into the cell against their concentration gradient. This is an example of which type of transport? symport ABC transport antiport facilitated diffusion

Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
