Explain how one receptor can induce different phenotypes in different cell types.

Biology

GaryK [48]3 years ago

Answer:

Different cell types are specialized to respond to signals in different ways regardless of the receptor because the intracellular signals produced are interpreted differently in cells specialized for different functions.

Explanation:

Different cells types with the same kind of receptor for signals can induce different phenotypes due to difference in the intracellular responses produced by the cell types because of the difference in functions performed by the cells. For example, acetylcholine binds to similar receptors in different cell types but illicit different response in them. Acetylcholine signals in heart muscle cells cause reduction in the rate and force of contraction of the heart; also acetylcholine cause secretion in the salivary gland cells; also contraction upon introduction into the skeletal muscle cells despite binding to similar receptors in all the cell types mentioned. The response produced are as a result of the different specialized functions performed by those cell types not minding the receptor component and its foreknown action.

Answer:

It is possible since a receptor can activate different signaling pathways in different cell types  

Explanation:

In a cell, a receptor bind to a specific ligand to activate a signaling pathway, while the same receptor may bind either with the same or another ligand in another cell type and thus activate another signaling pathway

The organismal theory teaches that _____.
natita [175]

Answer:

A. the basic unit of life is the organism

Explanation:

According to the organismal theory, organisms are the basic unit of life. The organismal theory contradicts the cell theory of life. The organismal theory states that some of the organisms do not have distinct cells. For example, fungi.

Since the cells in the multicellular organisms are interconnected by one or other means, organisms are the structural unit of life; not the cells.

The organismal theory states that irrespective of the level of body organization present in an organism, all the components such as cells, tissues, organs, etc. work together to facilitate growth and development of whole organisms.

Name the quadrant(s) (RUQ, LUQ, RLQ, and LLQ) and region(s) (right hypochondriac, epigastric, left hypochondriac, right lumbar,
andreev551 [17]

Answer:Answer: 1) (a) The left lobe of the Liver is located in Left Upper Quadrant while the main part of the Liver is located in the Right Upper Quadrant.

(b) The liver is located in both the right hypochondriac region and the epigastric region

2) (a) The stomach is is located in the Left Upper Quadrant (LUQ)

(b) The stomach is majorly located in the epigastric region and the Left Hypochondriac Region.

3) (a)The Spleen is located at the Left Upper Quadrant (LUQ)

(b) The regions the Spleen are located at are the Left Hypochondriac Region, Epigastric Region and Left Lumbar

4) (a) The Gall Bladder is located at the Right Upper Quadrant

(b) The Gall Bladder is located at the Right Hypochondriac Region and the Right Lumbar Region.

5) (a)The Appendix is located in the Right Lower Quadrant

(b) The Appendix is located in the Right Iliac region.

6) (a) The Left kidney is located at the Left Upper Quadrant

(b) The left kidney cuts across the Left Hypochondriac Region, Right Lumbar and the Left Lumbar.

7) (a) The right Ovary is located at the Right Lower Quadrant

(b) The region of the right ovary is the hypogastric region.

8) (a) The Uterus is located at both the Right Lower Quadrant and Left Lower Quadrant.

(b) The Uterus is located in the hypogastric region of the abdomen.

Explanation: In medicine, the practitioners divide the lower part of the body known as the 'abdomen' with imaginary lines ( one vertical and one horizontal) to form the 'Quadrants' and (two vertical and two horizontal) the 'Regions'. The Quadrants are divided into four main parts:

1) Left Upper Quadrant (LUQ)

2) Right Upper Quadrant (RUQ)

3) Left Lower Quadrant (LLQ)

4) Right Lower Quadrant (RLQ)

The regions are divided into nine parts:

1) Left Hypochondriac Region

2) Right Hypochondriac Region

3) Epigastric Region

4) Left Lumbar Region

5) Right Lumbar Region

6) Umbilical Region

7) Right Iliac/Inguinal Region

8) Left Iliac/Inguinal Region

9) Hypogastric Region.

The abdomen is divided into regions in order to help medical practitioners and students easily understand the abdominal area of the body as well as the human anatomy. It also helps them provide preliminary diagnosis and treatment based on pain emanating from each region or quadrant.
