[whats-in-a-sentence]

The systemic production of proteinase inhibitors in young tomato plants is triggered by a complex sequence of events (Figure 23.20):

Wounded tomato leaves synthesize prosystemin, a large (200 amino acids) precursor protein.

Prosystemin is proteolytically processed to produce the short (18 amino acids) polypeptide DAMP called systemin.

Systemin is released from damaged cells into the apoplast.

In adjacent intact tissue (phloem parenchyma), systemin binds to a pattern recognition receptor on the plasma membrane.

The activated systemin receptor becomes phosphorylated and activates a phospholipase A2 (PLA2).

The activated PLA2 generates the signal that initiates JA biosynthesis.

JA is then transported through the phloem to systemic parts of the plant by an unknown mechanism.

JA is taken up by target tissues and activates the expression of genes that encourage proteinase inhibitors.

ok but this sentence was on another diagram she shared:

"cells constantly replace their ATP by whacking a spare phosphate onto ADP"

how delightfully informal! i'm guessing this is British English? but even there I can't imagine this is typical academic textbook language, right? the rest of the sentence was the normal dry explanation.

ATP is a phosphorylating agent (that is, it donates phosphates to other molecules) in many biochemical processes, where it acts as an energy source.

Phosphorylation:Metabolic Pathway

Phosphorylation: The Powerhouse of Cellular Energy In the bustling world of cells, energy is the driving force behind every process, from building proteins to transporting nutrients. And one of the most crucial players in this energy-generating game is phosphorylation. What is Phosphorylation? Phosphorylation is the process of adding a phosphate group (PO43-) to a molecule. This process can…

I could post the entire transcript of destiny deoxys as a text wall just to be annoying, and nobody could stop me. Do you ever sit and think about the power at your fingertips? Because I do.

#not a threat. just an option. #back to exam studying. sigh. #the one i found kind of sucks though. naturally my brain goes 'well. if you want it done right then do it yourself'. #as if that's at ALL a good use of my time. it's absolutely not. i won't do it. for now. but I could. #the urge to sink hours into something tedious/boring/unasked for/unrewarding..... it tempts me more than studying does. I'll say that much #being bored will have you wondering 'hm. what if i hole punched an entire piece of paper for fun' #or 'hm. what if I transcribe this entire movie from like 2006 for literally no reason other than it's-not-phosphorylation'

2 final exams day is OVER!! ended up with an A in chinese😋 and im reluctant to get my hopes up bc i felt great about the midterm and ended up just getting a 78 but secretly i feel like i mega slayed the signal transduction final

#adderall is a fucking miracle drug my memory/recall is back to how it used to be before i got all depressed #like i remembered the specific residues that got phosphorylated in different pathways and stuff like that #anyways i felt really good about it i hope i actually did good and im not just delusional about my own intelligence

One of these experiments, carried out by Emerson, measured the quantum yield of photosynthesis as a function of wavelength and revealed an effect known as the red drop (Figure 7.12). (...) The observation that the overall quantum yield of photosynthesis is nearly independent of wavelength (see Figure 7.12) strongly suggests that such a mechanism exists.

Why are so many people so bad at explaining energy transfers? It's already complicated enough, why ya gotta make it even more confusing?

#I'm not even sure if 'energy transfer' is the right term #BECAUSE EVERYONE IS SO GODDAMN METAPHORICAL IN THEIR LANGUAGE #which. i appreciate they intent to make it all 'relatable' or whatever. but it just makes it unclear. #and then i end up doubting the few things that i did think i understood #grr. #anyway. i'm like PRETTY sure that it always takes energy to break chemical bonds. and the release of energy comes from forming the new bonds #but everyone seems to abbreviate that to 'bond that releases energy when broken' #(and i literally copied that from a diagram my professor shared) #which makes me feel like im being gaslit or something #or that I've completely misunderstood how chemical energy works. #and i HATE it #idk. maybe i'm too literal minded and pedantic or something. but i feel like it goes beyond a simplification into 'confusing factual error' #gillianthecat goes back to school #hw lb #microbiology #energy #atp #phosphorylation

The factors that determine these changes are not completely understood, but changes in the phosphorylation state of PINs mediated by the kinase PINOID and the phosphatase PP2 can have significant effects on PIN localization.
