Adenine (A):Adenine is a purine with the chemical compound C5H5N5. An Adenine-based nucleotide is calledadenosine. Adenine is formed by two hydrogen bonds, which help stabilize nucleic acid structures.ATP (adenosine triphosphate)is also an important form of energy, found in most cellular function...
Prosenchyma cells arestarch-containing parenchymal cells whose cell walls have become lined with lignin, as occurs in the stems of Bougainvillea (Nyctaginaceae). A specialized type of parenchyma cell, called a transfer cell, is involved in the short-distance movement of solutes by cell-to-cell ...
What is ATP in biology? Besides making ATP, what are two things cells power with proton gradients? 1. What is ATP? 2. What is ADP? 3. Why does energy need to be transferred from glucose to ATP? Which of the following options is correct? The driving force of facilitated diffusion...
DNA is located within the nucleus of the cell and is always double-stranded in living organisms. DNA houses genes, which are permanent from the day that someone is conceived until their death (given there are no mutations). RNA on the other hand is transient within the cell and ...
which is then fixed by rubisco and made into sugars in the Calvin cycle (just like C3 photosynthesis). C4 plants are better adapted to hot, dry environments and can continue to fix carbon even when their stomata are closed (as they have a clever storage solution), according to Biology ...
This is carbon fixation, or fixing inorganic carbon into organic molecules that the plant can use: 3 CO2+ 6 NADPH + 5 H2O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H++ 6 NADP++ 9 ADP + 8 Pi(Pi= inorganic phosphate) ...
Unfortunately, the definition of a healthy donor is less straightforward. Currently, donors are selected primarily to exclude known pathogens and mitigate the risk of transferring infectious diseases [15–18]. While ensuring recipient safety is a priority above all, research on optimal donor selection...
Deoxyribonucleic acid, or DNA, may be the most famous single molecule in all of biology. The discovery of its double-helix structure in 1953 catapulted James Watson and Francis Crick a Nobel Prize, and even among non-science nerds, DNA is widely known for playing a major part in the innum...
RCRA has a precise and technical definition for solid waste, and it covers a lot of territory. The law states that it isany garbage, refuse or abandoned material. Interestingly, it is considered "solid" even though it may be a liquid or gas, so water that contains dissolved waste would ...
Explain the processes of ATP hydrolysis and ADP phosphorylation. Describe how ATP is produced in mitochondria from the products of the previous steps of cellular respiration (NADH and FADH_2). (Via the electron transport chain) Explain the TCA cycle and the electron transport chain. ...
