Select all that apply. The sodium-potassium ion pump: hydrolyzes ATP, utilizing the free phosphate ion to temporarily bind to the transport protein. opens a channel through the membrane by phosphorylating one subunit of the transport protein. D is the only known ion pump. D is mediated by one enzyme that both hydrolyzes ATP and transports the ions. can be run in reverse, phosphorylating ADP to ATP Which of the following describes secondary active transport? O The antiport...

1) According to the chemiosmotic theory, the synthesis of 1 mole of ATP is coupled to the movement of 4 moles of H ions across the inner mitochondrial membrane (from outside to inside). Both the pH and the electrostatic potential (φ) can be different on different sides of the cell membrane as maintained by metabolic processes. a) Derive an expression for AG for the movement of 4 moles of H from outside the membrane to inside the membrane. Your expression...

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...
