The maximum psi strength of JB Weld when used for bonding materials together is typically around 3960 psi.
What is the boiling point of ethane at 175 psi?

How many ounces of gas pressure is 6 of water column?
1 psi (pound per square inch) is equivalent to 27.7 inches of water column. Therefore, 6 inches of water column is approximately 0.216 psi. To convert psi to ounces per square inch, we can use the conversion factor: 1 psi = 2.036 oz/in^2. Therefore, 6 inches of water column is equivalent to approximately 0.44 oz/in^2.
What is the maximum psi for titanium without breaking?
Commercial grade Titanium (92% pure) is 63,000 psi (434 MPa). Certain titanium alloys (e.g., Beta C) achieve tensile strengths of over 200,000 psi (1,400 MPa). Megapascal or MPa is a unit to measure tensile strength.
How are the chlorophyll molecules in PSI and PSII reset?
The chlorophyll molecules in Photosystem I (PSI) and Photosystem II (PSII) are reset when an electron is donated to them from an external source, such as when water is split during the light-dependent reactions of photosynthesis. This replenishes the electrons lost during the light-harvesting process, allowing the chlorophyll molecules to continue their role in capturing and transferring light energy.
What special pigment do plant cells contain?
Chlorophyll in the chloroplasts and other accesory pigments (p680 in PSII and p700 in PSI)
Why photolysis of water takes place at PSII and not at PSI in thallakoid channel?
Photolysis of water occurs at Photosystem II (PSII) because it has a higher oxidation potential than Photosystem I (PSI). This higher potential allows PSII to extract electrons from water molecules during the light-dependent reactions of photosynthesis. Additionally, the location of the water-splitting complex is specific to PSII, where it is positioned near the oxygen-evolving complex that facilitates water splitting.
What is the difference between PSI and PSII?
PSI (Photosystem I) and PSII (Photosystem II) are two different protein complexes in the thylakoid membrane of chloroplasts involved in the light-dependent reactions of photosynthesis. PSII functions first in the electron transport chain by absorbing light energy to oxidize water and generate oxygen, while PSI receives electrons from PSII and drives the production of NADPH for the Calvin cycle.
What is one way photo system 2 and photo system 1 are simmalar and one way theur diffrent?
Both Photosystem II (PSII) and Photosystem I (PSI) are integral components of the photosynthetic electron transport chain in plants, algae, and cyanobacteria, and they both play crucial roles in capturing light energy to drive the process of photosynthesis. However, they differ in their functions; PSII primarily captures light energy to split water molecules and generate oxygen, while PSI primarily facilitates the reduction of NADP+ to NADPH. Additionally, PSII operates earlier in the light-dependent reactions compared to PSI.
What catches sunlight during photosynthesis?
Photo systems embedded on the thylakoid membranes catches light. photo systems are of two type PSII and PSI. photo systems consists of chlorophyll and accessory pigments. these catch the sunlight for the process of photosynthesis.
What are the clusters of photosystems?
The two clusters of photosystems in plants are Photosystem I (PSI) and Photosystem II (PSII). PSII functions first in the photosynthetic electron transport chain, followed by PSI, and they work together to absorb light energy and carry out the reactions of photosynthesis.
How is H electrochemical gradient established and maintained in photosynthesis?
The formation of NADPH, the movement of electrons from PSII to PSI, & the splitting of water
How is light energy processed in the light reaction of photosynthesis?
In simple terms, photosynthesis is the conversion of carbon dioxide (CO2) to carbohydrate (CH2O). To do this two things are needed: energy to drive the reaction and a source of hydrogen. The light reaction of photosynthesis produces two essential substances: ATP and NADPH. ATP provides the energy for the conversion of CO2 to CH2O, and NADPH provides the hydrogen. The light reaction depends on groups of chlorophyll molecules, called photosystems, absorbing light energy. The energy is used to eject high energy electrons from the chlorophyll. The energy in the electrons is then used to make ATP and NADPH. There are two photosystems, called photosystem I (PSI) and photosystem II (PSII), which work in sequence. (PSII comes before PSI in the sequence, but they were discovered and named in the reverse order!). PSII absorbs light and emits a high energy electron. The energetic electron then passes down a series of molecules, called an electron transport chain (ETC), releasing energy as it goes (you can visualise it as a ball bouncing down a set of stairs, losing energy as it falls). The energy released is used to make the energy carrier compound ATP. To replace the electrons lost from chlorophyll in PSII water (H2O) is split into hydrogen ions (H+), electrons (e-) and oxygen atoms (O): H2O = 2H+ + 2e- + O This is the source of the oxygen released by photosynthesis. The second photosystem, PSI, also absorbs light and emits a high energy electron from chlorophyll. The energy in this electron is used to drive the synthesis of NADPH from NADP+ ,hydrogen ions (H+) and electrons (e-): NADP+ + 2H+ + 2e- = NADPH + H+ The hydrogen ions needed for this come from the water which was split by PSII. The electrons lost from the chlorophyll in PSI are replaced by the electrons ejected from PSII. The result of all this is that light energy is converted into chemical energy in ATP, water is split to provide the hydrogen needed to make NADPH, and oxygen is released as a waste product. The ATP and NADPH are then used in the light independent reaction (the Calvin cycle) to concert carbon dioxide into carbohydrate.
What photosystems are embedded in the electron transport chain?
PSII, PSI, cytocromes, ferrodoxins are the part of ETC. They transport the protons to ATPase to produce ATP.
What is the difference between photosynthesis I and photosynthesis II?
Photosynthesis II or PS II (photosystem II) comes before PS I. PSII uses a pair of P680 chlorophyll a, while PSI uses a pair of P700 chlorophyll a. These systems populate the thylakoid membrane.First, light hits PS II and excites its pigment molecules and the energy bounces off the pigment molecules until it gets to the P680 chlorophyll and excites its electrons which then causes it to give off an electron to the Primary electron acceptor.Now the pair of P680 is deprived of an electron, this is where water comes nto play. An enzyme catalyzes the splitting of water to produce O2 and two electrons, these electrons supply the ones that the pair of P680 chlorophyll gave away, this enables the P680 to be able to get excited again and again without being deprived of electrons.Back to the primary acceptor, the excited electron passes from PS II to PS I via the Electron Transport chain. This produces ATP.The electron then is at the P700 pair of chlorophyll a's of PS I which excites it and it gives off that electron to another primary electron acceptor which transports its electrons via ETC as well, but the final electron acceptor is NADP+, which with the electron becomes: NADPH.
Write the equation connecting photo system 1 and photosystem 2?
The equation connecting Photosystem I (PSI) and Photosystem II (PSII) in photosynthesis is: 2H2O + 2NADP+ + 8 photons (light) → O2 + 2NADPH + 2H+ + 8 photons (light). This represents the light-dependent reactions in the thylakoid membrane where PSII and PSI work together to drive the production of energy carriers like ATP and NADPH.
