How do basal cells contribute to olfaction?
Expert Solution & Answer
Summary Introduction
To review:
The contribution of basal cells in olfaction.
Introduction:
A chemoreception, which creates the sense of smell, is called as olfaction. This chemoreception has many other purposes apart from the sense of smell. These are the detection of hazards, food, and pheromones. The sense of flavor is formed when olfaction integrates with other senses.
Explanation of Solution
The nose is the primary organ for olfaction. It consists of olfactory receptor cells, supporting cells, and basal cells. Olfactory receptor cells are considered as the first-order neurons of olfactory pathway. The cilia are present as the site for olfactory transduction. Supporting cells refer to the columnar epithelial cells belonging to the mucous membrane that lines to the nose. On the other hand, basal cells refer to the stem cells that is situated between the bases of the variety of supporting cells. These basal cell undergoes cellular division in order to release newly formed olfactory receptor cells. These receptor cells live for about 2 months before being substituted. This process is phenomenal because the olfactory receptors cells are the neurons and matured neurons are not usually replaced.
Conclusion
Therefore, it can be concluded that basal cells are involved in the cellular division in order to generate new receptor cells for olfaction.

*Example 2: Tracing the path of an autosomal dominant trait
Trait: Neurofibromatosis
Forms of the trait:
The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein
neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous
tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a
cancerous form. i
The recessive form is a normal protein - in other words, no neurofibromatosis.moovi
A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not
indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis
allele, and the letter "n" for the normal allele.

- 9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
