Most of the metabolic activity in a cell occurs in the mitochondrion. This organelle is responsible for the generation of ATP through a process known as oxidative phosphorylation.
Both fatty acids and carbohydrates are metabolized inside the mitochondrion. The purpose of this breakdown is to produce as much ATP as possible through the process of glycolysis and the citric acid cycle. The ATP is then used to fuel other processes occurring in the rest of the cell.
The mitochondrion is a unique organelle as it has its own variant of DNA. This allows the organelle to produce its own proteins, tRNAs and rRNAs. It is thought that mitochondria originally began life inside bacterial cells, but transferred to complex eukaryotic cells later on. This is known as the endosymbiotic theory.Learn More
ATP is called the energy currency of the cell, and of life, because it is the energy molecule that all cells need in order to do anything within the human body. The molecule is used like a battery within cells and allows the consumption of one of its phosphorous molecules.Full Answer >
Ribosomes are composed primarily of ribonucleic acid and proteins. They are responsible for the translation of genetic data from amino acids into simpler proteins for use in cell functions.Full Answer >
Certain types of bacteria can cause diseases, such as, typhoid fever, syphilis, cholera, tuberculosis and foodborne illnesses. Antibiotics are used to kill harmful bacteria and the diseases they cause.Full Answer >
The Calvin cycle takes place in the stroma of the chloroplast. Carbon dioxide enters the stroma of the chloroplast to combine with the five-carbon compound called ribulose1, 5-Biphosphate to form two molecules of a three-carbon compound called 3-Phosphoglyceric acid. This reaction is catalyzed by an enzyme called Ribulose bi-phosphate Carboxylase.Full Answer >
