Okay so tomorrow we’re taking a test and we’re allowed our notes (but we have to write it all on one sheet of paper).

I’m kinda confused as what to write…

I’m in Honors Biology 9 (Freshie in High School, basically). I need to have

Glycolysis
The Krebs Cycle
And Photosynthesis.

As well as all of their equations n’ stuff, as well as ATP definitions and what they can turn into and what they do.

Iiiiiiii have no idea how to translate this onto a piece of paper

Sooooo I turned to y’all.

@SaltyLasagna

Drawing the process usually helps, and I've got some definitions that I reworded into ridiculous things because it's easier for me to understand when it's in my language lmao

@SaltyLasagna

k it might take me a while to find it though bc I wrote them last year and my school googlie drive is filled with a bunch of bullshit lol

@SaltyLasagna

as for the equations, I can't really help you there other than just do your to remember it. When I have to memorize equations I just kinda write them down over and over and over again, sing them, write them backwards, write them with my eyes closed…. I kinda go all out lmao

@SaltyLasagna

Ew parents

Well ima go get food

Is our RPs still a thing

yes yes of course
I'm sorry I've been abandoning them, I'm just not comfortable going on the chromebook and doing them and I haven't had any time to get to my laptop lately

@SaltyLasagna

So basically
Mitochondria make ATP (not really a part of cellular respiration but ATP is a big part of it)
ATP is like, the energy for pretty much everything. It's the "universal energy molecule".
Also, the energy molecules in cellular respiration are divided into two parts. High energy molecules and low energy molecules.

Low Energy

  • NAD+
    -ADP

(side note: to me, the "+" on the low energy molecules is kind of off putting because "+" is associated with something positive/higher. Just remember that NAD+ is deceiving, the "+" does not mean high energy in this case)

High Energy

  • ATP
  • NADH

(for me, these are the most difficult things to remember. I'm not sure if you'll be tested on them or if you'll even learn them, but due to how fucking boring and uninteresting they are, it can be difficult to get down, at least for me.
now, here are my exact notes I took on Cellular Respiration. If you want, I could put them into a quizlet and link it to you, I seriously recommend using quizlet for this, they really help me especially when I'm cramming.
also I couldn't find the notes where I converted everything into my own words. I probably titled it something really fucking weird and can't remember what it was so I can't find it, sorry…)

Cellular Energy

  • All life requires the use of energy
  • Many organisms obtain their energy from eating other organisms
  • Autotroph: makes their own food
  • Heterotroph: eats other organisms for food

ATP

  • ATP is the universal energy molecule
  • Used to power most of your bodily functions
  • Muscle contraction
  • Build up of Na/K gradients

High Energy vs Low Energy

High Energy

  • NADH
  • ATP

Low Energy

  • NAD+
  • ADP

Cellular Respiration

  • The process of taking high energy molecules and slowly releasing the energy stored in the chemical bonds
  • Remember non polar covalent bonds have the most stored energy
  • Glucose has 5 non polar covalent bonds holding the carbons together

Why Slowly?

  • To collect as much energy as possible

Cellular Respiration

Three main Steps

  • Glycolysis
  • Krebs Cycle
  • Electron Transport Chain

  • First Step: Glycolysis
  • High energy in
  • 2 ATP
  • High energy out
  • 2 NADH
  • 4 ATP
  • Happens in cytoplasm

Second Step: Krebs Cycle

  • Pyruvate is converted into Carbon Dioxide
  • Lots of NADHs are made (8 NADH)
  • Happens in Mitochondria

Third Step: Oxidative Phosphorylation

  • Takes NADH and builds a H+ gradient
  • Uses gradient to power ATP synthase

Okay neato thank you!

You actually gave me too much but that’s okay!

@SaltyLasagna

oof sorry
I also have very specific notes on all of the steps of photosynthesis and cellular respiration and can trim it down for you if you want me to, and add anything you need (please let me help one of the only reasons I go to school everyday is because I love biology)

(Lmao)

Um I need ATP and ABT (i think that’s what it is?) and I need more on the Krebs, Glycolysis and Photosynthesis and the chemical formulas, steps n where they happen

@SaltyLasagna

okay those I can definitely do
how much more do you need on ADP and ATP? Like I can give you the structure and how they're made and what they do but that's not on the cells and energy portion of my test? (teachers teach differently though I guess)

@SaltyLasagna

okay so ummm it turns out i don't have any notes on ATP/ADP production, I thought I did but I actually just have notes on cellular functions RIP

Glycolysis is pretty simple though. It breaks down glucose (sugar) and requires very little energy to start the process. It produces high energy molecules (2 ATP go in and 4 come out, as well as 2 NADH. Those are both high energy molecules)

Oof

Kk thank you. I’ll be copying this down the moment I feel like it.
