It was not until the year of 1952!
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
It was exposed to oxygen. This is called oxidation and it's a chemical reaction, meaning it can't be reversed.
Body's major metabolic hormone is called Thyroid hormone
Answer:
DNA
Explanation:
Deoxyribonucleic acid (DNA) is known as the hereditary material of cells. It carries information for coding all type of proteins in the body.
As helicases are proteins, the genetic code from which they are to be made would be present in a specific sequence on part of DNA. This code would be transcribed and mRNA will be formed. After this, the mRNA will be translated and modified into a helicase enzyme.
