Concept explainers
(a)
To determine: Whether the neuron will hyperpolarize or depolarize from resting membrane potential of -70 mV if sodium ion enters the cell.
Introduction: Neuron is the structural and functional unit of the nervous system. It can be hyperpolarized or depolarized based on the movement of different ions inside and outside of the cell.
(b)
To determine: Whether the neuron will hyperpolarize or depolarize from resting membrane potential of -70 mV if potassium ion leaves the cell.
Introduction: Neurons help in the generation of action potential and graded potential to transmit the information inside the body; the electrical conductivity of the neuron changes by the inward and outward movement of ions.
(c)
To determine:Whether the neuron will hyperpolarize or depolarize from resting membrane potential of -70 mV if chloride ions enter the cell.
Introduction: Neurons transmit the information from one neuronal cell to the other. The human brain contains millions of neurons.
(d)
To determine: Whether the neuron will hyperpolarize or depolarize from resting membrane potential of -70 mV if calcium ions enter the cell.
Introduction: Neurons can receive or send a message from one part of the body to the other. The electrical conductivity of neurons occurs due to unequal distribution of ions in and out of the cell.

- The Sentinel Cell: Nature’s Answer to Cancer?arrow_forwardMolecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forward
- Molecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell.
