- Which of the fallowing is required to generate a membrane potential? I. A concentration gradient of ions II. Presence of neurotransmitters II. Semipermeable membrane a) II only b) I only c) II and III d) I and IIIarrow_forwardGap junctions are dynamic structures that, like conventional ion channels, are gated: they can close by a reversible conformational change in response to changes in the cell. the permeability of gap junctions decreases within seconds, for example, when the intracellular Ca2+ concentration is raised. speculate why this form of regulation might be important for the health of a tissue.arrow_forwardThe negatively charged intracellular environment and resulting resting membranepotential of neurons and muscle cells fundamentally develops because of:A. the presence of a high extracellular potassium concentration.B. the presence of negatively charged intracellular proteins.C. the high electron concentration found in the extracellular fluidsD. the presence of voltage-gated-sodium channellsarrow_forward
- Nitric oxide (NO) is a gaseous molecule with lipid solubility similar to that of O2 and CO2. Endothelial cells lining arteries use NO to signal surrounding smooth muscle cells to relax, thereby increasing blood flow. What mechanism or mechanisms would transport NO from where it is produced in the cytoplasm of an endothelial cell into the cytoplasm of a smooth muscle cell, where it acts?arrow_forwardWhich of the following statements is a lie? Select one: a. The contractile ring further contracts until the membrane becomes completely cleaved into two. b. Cytokinesis occurs differently in animal and plant cells. c. Cytokinesis is more complex in animal cells than in plant cells.arrow_forward8) The diffusion of K+ out of the cell makes the inside of the cell less positive, or more negative, and acts to restore the original resting membrane potential. This process is called: a) depolarization b) hyperpolarization c) repolarizationarrow_forward
- Calcium plays a role in ____ because it allows the interaction between the plasma and vesicle membranes: a- Synaptic vesicle re-uptake b- Synaptic vesicle specialization c- Synaptic vesicle information d- Synaptic vesicle fusion with the plasma membranearrow_forwardRank the following by their ease of crossing the plasma membrane: a. Easiest - Ca2+ - H2O - O2 - Hardest b. Easiest - H2O - O2 - Ca2+ - Hardest c. Easiest - O2 - H2O - Ca2+ - Hardest d. Easiest - Ca2+ - O2 - H2O - Hardestarrow_forwardThe resting membrane potential is established by? The Na+/K+-ATPase pumping Na+ into the cell and K+ out of the cell The Na+/K+-ATPase pumping K+ into the cell and Na+ out of the cell A larger diffusion of K+ out of the cell compared to diffusion of Na+ into the cell A larger diffusion of K+ into the cell compared to diffusion of Na+ out of the cell a) and d) b) and c)arrow_forward
- How are vesicles with neurotransmitter transported to the synaptic cleft? A. Retrograde, slow transport. B. Anterograde, slow transport. C. Retrograde, fast transport. D. Anterograde, fast transport.arrow_forwardA cell biologist is performing an experiment using the voltage clamp method in which they are allowed to change the voltage in the membrane potential. They are wanting to record potassium currents and notice that for a certain membrane potential range, the voltage clamp highlights that there is an inward current of potassium. Would these readings make sense?arrow_forwardYou are watching cells in a dish spontaneously contract. They are all contracting at different rates; some fast, some slow. After a while, several cells link up and they begin contracting in synchrony. Discuss what is going on and what type of cells you are looking at.arrow_forward
