2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons to become stable
3. Nucleic acids are organic molecule composed of nucleotides. The role of nucleic acids are to store, express, and transmit genetic information. A nucleotide is an organic molecule having three components: one or more phosphate groups, a five carbon sugar, and a single or double ring of carbon and nitrogen atoms. Two types of nucleic acids are DNA and RNA. RNA. The structure of DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.
4. Eukaryotic cells and prokaryotic cells both have DNA genetic material. They both are bounded by a …show more content…
Fermentation is the breakdown of organic molecules to produce energy without any net oxidation of an organic molecule. The pathways pf breaking down glucose to lactate or ethanol are examples of fermentation. Although electrons are removed from an organic molecule such as glucose to make pyruvate and NADH, the electrons are donated back to an organic molecule in the production of lactate or ethanol. Therefore, there is not removal of electrons from an organic molecule. Compared with oxidative phosphorylation, fermentation produces far less ATP for two reasons. First, glucose is not oxidized completely to carbon dioxide and water. Second, the NADH made during glycolysis cannot be used to make more ATP. Overall, the complete breakdown of glucose in the presence of oxygen yields 34 to 38 ATP molecules. By comparison, the anaerobic breakdown of glucose to lactate or ethanol yields only 2 ATP
