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.Know More
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 about Cells
Dr. William H. Heidcamp, a professor in the Biology Department at Gustavus Adolphus College, explains that cell differentiation occurs when the structure and function of cells change within a certain period. The formation of the three germ tissues of embryos, which are the endoderm, ectoderm and mesoderm, is a classical approach to the basic process of cellular differentiation.Full Answer >
Aerobic respiration on the cellular level occurs in the cell's mitochondria, according Georgia State University. Respiration transforms pyruvate into adensoine triphosphate through the TCA cycle in mitochondria. The TCA cycle, also known as the Krebs cycle, uses enzymes to transport electrons among water, oxygen, carbon and other atoms.Full Answer >
Glycolysis occurs in the cytosol (cytoplasm) of the cell. Glycolysis is the first of the three metabolic processes that make up cellular respiration. Cellular respiration produces the adenosine triphosphate, or ATP, used by cells for energy.Full Answer >
The ribosomes in the cytoplasm are the sites of protein translation in the cell. Translation refers to taking a copy of messenger RNA, or mRNA, and making a protein from the code.Full Answer >
