the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
A) A chain volcano would typically be found under a convergent boundary.
Answer:
volume = 0.285 L
Explanation:
Henry constant is given as
![Henry constant = \frac{C}{P}](https://tex.z-dn.net/?f=Henry%20constant%20%20%3D%20%20%5Cfrac%7BC%7D%7BP%7D)
Where C is concentration
P is atmospheric pressure
![Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm](https://tex.z-dn.net/?f=Henry%5C%20constant%20%3D%20%5Cfrac%7B0.00056%7D%7B0.80%7D%20%3D%200.0007%20M%2Fatm)
when atmospheric pressure 4 atm
![solubility = K_H\times P](https://tex.z-dn.net/?f=solubility%20%3D%20K_H%5Ctimes%20P)
![= 0.0007 \times 4 = 0.0028 M](https://tex.z-dn.net/?f=%20%3D%200.0007%20%5Ctimes%204%20%3D%200.0028%20M)
In 5 litere blood , moles of N_2 ![= Molarity \times volume](https://tex.z-dn.net/?f=%20%3D%20Molarity%20%5Ctimes%20volume)
![= 0.0028 \times 5 = 0.014](https://tex.z-dn.net/?f=%3D%200.0028%20%5Ctimes%205%20%3D%200.014)
At surface moles ![= 0.0056 \times 5 = 0.0028](https://tex.z-dn.net/?f=%3D%200.0056%20%5Ctimes%205%20%3D%200.0028)
Moles of N_2 release = 0.014 - 0.0028 = 0.0112
Mass of ![N_2 = 0.0112 \times 28 = 0.314 g](https://tex.z-dn.net/?f=N_2%20%3D%200.0112%20%5Ctimes%2028%20%3D%200.314%20g)
T = 37 + 273 = 310 K
![VOLUME = \frac{nRT}{P}](https://tex.z-dn.net/?f=VOLUME%20%3D%20%5Cfrac%7BnRT%7D%7BP%7D)
![= \frac{0.0112\times 0.0821\times 310}{1}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.0112%5Ctimes%200.0821%5Ctimes%20310%7D%7B1%7D)
volume = 0.285 L
Answer:
There is no regulatory protein that oxidizes these Calvin cycle enzymes; oxidation is spontaneous.
Explanation:
Four enzymes of the Calvin cycle are regulated by sunlight. These enzymes are namely Ribulose 5-phosphate kinase, fructose 1,6-bisphosphatase, sedoheptulose 1,7-bisphosphatase, and glyceraldehyde 3-phosphate dehydrogenase.
The inactive form of these enzymes has disulfide bonds between two Cys residues. In the presence of sunlight, the reduced thioredoxin that obtains electrons from PS-I via ferredoxin reduces the disulfide bonds between the Cys residues of these enzymes.
The reduction of the bonds brings about the confirmation changes to make the enzyme active.
At nightfall, these bonds are spontaneously re-oxidized and there is no reduced thioredoxin available to reduce them again. The spontaneous oxidation of the disulfide bonds of these enzymes at nightfall makes them inactive again.
