from atoms, atoms through a certain force, arranged in a certain order and combined into molecules. A case study of water molecules, water constantly separated forever until without damaging properties of water, there is the smallest unit of made up of two hydrogen atoms and one oxygen ato ...
Fermentation is a process of extracting energy from carbohydrates in the absence of oxygen. The energy extracted through the series of biochemical transformations is stored in the ATP molecules. The process of fermentation is coupled with glycolysis as a part of anaerobic res...
The resulting hybrid molecules consisting of 3,5-diaryl isoxazoline or isoxazole linked with quinazolinone by various alkane spacers were assayed for their anticancer activity. One of the most active compounds was an isoxazole derivative 49, which in a cytotoxic assay against A549 cell line (...
Which of the following molecules is called the energy currency of the cell, because it allows the energy released the from breakdown of molecules to be stored and exchanged with reactions that require energy? a. glucose b. oxygen c. ATP d. ADP Which reactants get oxidized and which get re...
The oxygen saturation of Hb is mainly dependent on A、PO2 B、pH value in blood. C、concentration of 2,3-DPG. D、PCO2 E、temperature 点击查看答案 第6题 Water i___ a liquid made up of molecules of hydrogen and oxygen in the ratio of 2 to 1. 点击查看答案 第7题 The parties who...
It is all about how different materials are put together and made up of atoms and molecules. Additionally, chemistry is how these materials act under different conditions. Slime is a non-Newtonian fluid. A non-Newtonian fluid is neither liquid nor a solid. It can be picked up like a solid...
Hydrogen is the lightest element in the universe and the most abundant, so on paper, hydrogen fuel has a lot going for it. Although it rarely exists on its own on Earth, it can be produced using clean energy to split essentially inexhaustible water molecules, producing only oxygen as a by...
A hydrogen bond is a weak chemical bond that occurs between hydrogen atoms and more electronegative atoms, like oxygen, nitrogen and fluorine. The participating atoms can be located on the same molecule (adjacent nucleotides) or on different molecules (adjacent nucleotides on different DNA strands)....
Drones can also play a part in improving the health of millions of people. For example, an incredible development project by the University of South Australia is for drones to eventually be able to survey populations for disease by reading the blood oxygen levels of humans from the air. They...
Petroleum, also called crude oil, is a naturally occurring liquid found beneath the earth’s surface that can be refined into fuel. A fossil fuel, petroleum is created by the decomposition of organic matter over time and used as fuel to power vehicles, heating units, and machines, and can ...
