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.
Answer:
1 bacterial cell would contain 15N DNA
Explanation:
According to conservative model of DNA replication, the two DNA strands do not separate from each other and direct the synthesis of entirely new DNA molecule.
Here, a single bacteria had 15N DNA strands and then it was placed in N14 media. All the subsequent divisions would utilize 14N.
After one division: One 15N DNA and one 14N DNA
After two divisions : One 15N DNA and three 14N DNA
After three divisions: One 15N DNA and seven 14N DNA
Hence only one bacterial cell will contain 15N DNA
A population is the smallest unit of organisms that can evolve.
Answer:
doesn't it just show metals and non metals and their atomic number and mass number?
Explanation:
It comes from lightning and is named nitrogen fixation.
