Answer:
4. c) They result in production of diffusible second messengers
Explanation:
G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.
A list of the cell fibers from largest to smallest would read:
1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.
<span>2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and </span>other organisms like plants, fungi, unicellular organisms.
3. <span>Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the </span>cytoskeletons<span>. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.</span>
The answer is B. (The first answer above me is incorrect)
Fatty acids aren't pure fat and same for glycerol molecules. You may not be consuming straight fat, but things that create fat in your system.
Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
