Vaselesa [24]

Hai there :3 I'm planning to study chemical engineering.

Question related to Biochemistry (Photosynthesis & Cellular Respiration)

1. Chemiosmosis.  In the process of chemiosmosis, specific enzymes (such as ATP synthase) create ATP. Hydrogen ions go from a higher proton concentration to a lower one, which is why it's called chemio"osmosis"

2. Electron Transport Chain (ETC). The name says it all. Simply explained, electrons are transported and transferred in the mitochondrial membrane.

3. Oxygen. O2, the diatomic molecule, is essential in respiration. In the final stage of respiration, at the near end of the electron transport chain, oxygen accepts protons to become water. Cells use O2 during oxidative phosphorylation.

4. NADPH. I remember learning what this acronym means by heart. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen. NADPH is essential in photosynthesis as a typical coenzyme in the reduction of chemical reactions.

¿Dónde se encuentran los microorganismos? ¿Los microorganismos son signos de enfermedad?
Ilya [14]

Answer:

Microorganisms can be found both in the external environment  (ecosystem) and the internal environment (microflora) of higher organisms.

Explanation:

Microorganisms (microbes) are microscopic forms of life that include bacteria, protists, fungi and animal species, these organisms can se differentiated by using laboratory techniques such as the Polymerase Chain Reaction (PCR) or by microscopes. These organisms are both beneficial and both beneficial and pathogenic for humans. For example, the microflora may be useful in digesting nutrients contained in the food. On the other hand, <em>Plasmodium falciparum</em> is a pathogen microorganism that is found in the digestive system of mosquitoes and cause malaria in humans.

Iteru [2.4K]

Answer:

<em>If a cell in your body has 46 chromosomes, it is said to be diploid.</em>

Explanation:

A diploid cell can be described as a cell that has chromosomes present in it in the form of pairs. There are 23 pairs of chromosomes in the autosomal cells of a human body. This means that in total there are 46 chromosomes in the autosomal cells.

However, the sex cells of the humans are haploid. The sex cells of humans have 23 chromosomes. The male and female sex cells unite to form diploid cell.
