Answer:
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
Explanation:
Answer:
Carbondioxide and water
Explanation:
Cellular respiration is a metabolic reaction which occurs in the cells of organisms to convert biochemical energy to ATP which is in form energy and then releases it as waste product. The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of the cell to red blood cells, and back to your lungs to be exhaled.
According to Freud's psychoanalytic theory, rationality as well as logical thinking and reasoning are controlled by our a. pleasure principle because it can instinctively lead us to satisfy our basic needs which form logical sequence.
<h2>b) option is correct </h2>
Explanation:
- Some bacterial toxins cause disease by altering the activity of G protein, cholera toxin is one of them
- Cholera toxin catalyse ADP ribosylation of Gs and blocks GTPase activity thus Gs GTP become permanently active
- Constitutive activation of Gs protein continuously induce adenylyl cyclase, cytosolic cAMP level rises that leads to activation of protein kinase A (pKA)
- Activated pKA catalyse phosphorylation of two transmembrane proteins of intestinal epithelial cells:
- CFTR cause excessive outflow of Cl- ion and Na+ H+ exchange cause efflux of Na+ ion, both enters in gut and form Na+ Cl-
- Na+Cl- leads to outflow of water from the gut, resulting in diarrhea and dehydration and this condition may cause death of organisms due to loss of water and ions
