Cells can signal to each other in various ways. A signal that must be relayed to the entire body is most efficiently sent by ___________ cells, which produce hormones that are carried throughout the body through the bloodstream. On the other hand, ___________ methods of cell signaling do not require the release of a secreted molecule and are used for very localized signaling events. During ____________ signaling, the signal remains in the neighborhood of the secreting cell and thus acts as a local mediator on nearby cells. Finally, ____________ signaling involves the conversion of electrical impulses into a chemical signal. Cells receive signals through a _______________, which can be an integral membrane protein or can reside inside the cell.

Expert Solution

Endocrine (these are the glands which secret hormones.)
Contact dependent (here cell cell contact is required to pass on information. )
Paracrine ( here signal is weak and only works in neighbouring cells)
Neuronal( nerve cells transmit information by action potential and synapse).
Receptor( it is like receiver of information, may present on membrane like G protein receptor or may be inside the cell like receptor for testosterone).

Informal activity is naturally restricted in various ways from ever functioning as efficiently as it could were it completely legalized and freed from the restrictions that force the activity into informality. They include: Select one: a. informal production and commerce being subject to less risk because it operates outside the law. b. the lack of formal property rights in the informal sector, due to the fact that productive units do not technically exist and the owners of the property are...

*minimum 250 words You might find it amazing that most cells in the human body each contain at least one entire copy of your genome!!! That means a single cell has the genetic "blueprint" for your ENTIRE body! However, a particular cell does not "express" every gene found in your genome. How would you define "gene expression" in your own words?"

Both bacteria and phagocytic cells create toxins or harmful substances to attack each other. In most cases, these substances could intoxify themselves in the process. How do bacteria prevent toxic effectors from targeting themselves and how do phagocytic cells prevent harmful substances from damaging themselves?

1. Consider the cyanobacteria Anabaena. Individual cells grow attached to each other in long chains. Most perform photosynthesis, using photosystems I and II to generate ATP and NADPH that they use to power the fixation of carbon dioxide via the Calvin cycle. However, a small number form heterocysts, cell that instead of performing photosynthesis, fix nitrogen into ammonium. Heterocyts share their nitrogen compounds with their photosynthetic neighbors, who in turn share sugars with the heterocysts. a)If you extracted all the...

1. Steroid medications can usually be applied to the skin, whereas most other medications must be swallowed or injected. Using what you know about hydrophilic and hydrophobic ligands, explain why there is this difference. In your answer, make sure you describe in detail the pathway that a steroid and non-steroid medication would take to elicit their response. 2. You are interested in studying a new membrane receptor that you have identified, and think that it might be a receptor tyrosine...
