Study with Quizlet and memorize flashcards containing terms like Give the functions of water, Explanation of transport in water and give examples, Explanation of chemical reactions in water and give examples and more.
Hydrogen bonds between the oxygen of one water molecule and a hydrogen of another water molecule. Why does ice float on water? Because of cohesion, the space below the hydrogen bonds in water molecules increase when frozen.
The water provides 4 electrons, 4 hydrogen ions, and produces 1 oxygen molecule as a byproduct at photosystem 2. Sunlight is then captured by chlorophyll and provides more electrons that will then go through the electron transport chain.
Water is highly cohesive and adhesive: Because of hydrogen bonds, water molecules develop strong intermolecular attraction between them. This is called cohesion. When water form hydrogen bonds with other substance, the attraction is called adhesion.
17 Οκτ 2024 · Water is of great biological importance. It is the medium in which all metabolic reactions take place in cells. Between 70% to 95% of the mass of a cell is water. Water is composed of atoms of hydrogen and oxygen. One atom of oxygen combines with two atoms of hydrogen by sharing electrons (covalent bonding)
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules.
