A-LEVEL Respiration: Step 1 GLYCOLYSIS. Phosphorylation of glucose, making TP and Pyruvate.

Glycolysis is the first stage of aerobic respiration, but it also occurs in anaerobic respiration. Learn the three key stages in the biochemical reaction of glycolysis. I explain each stage in the reaction at A-level standard with visual diagrams.

Paper 2 is literally on Friday and I've never understood this in my life up until now thank you so much 😭😭😭😭😭

[hester]

You're a life saver! I was really struggling to get my head around the diagrams and phrasing my tutor uses, but watching this a couple of times really cleared things up for me! Many thanks :)

What do the arrows specifically show?
Like is it the reaction, a process..because adp to atp (sorry other way) could come first so

[meowcat]

great video! i do have a question though ☺️
you mentioned that glycolysis occurs in both aerobic and anaerobic respiration because it doesn’t require oxygen or energy (atp). however, the first step of glycolysis uses atp to phosphorylate glucose to glucose phosphate?

[juliettecurran]

Hi, we were taught that glucose is phosphorylated twice, first using one atp molecule to produce glucose phosphate and again to convert the glucose phosphate to hexose bisphosphate. Im guessing this is just an extra step so I was wondering if we need to know about hexose bisphosphate for the exam?

[richards]

hey miss could you explain how triose phosphate helps to turn 2adp to 2atp if it only has one phosphate?

[MrMidoo]

You are fabulous tutor🌹
I luv ur accent, it's so clear

[ImranAwan-ns]

Are the 3 videos on aerobic respiration in order on the playlist?

[sreejaanand]

Excellent video 👍🏽👍🏽thanks for sharing ❤

[lukehudd]

Just a question i came across- ‘Describe How pyruvate moves through the membrane (2marks)’ How would i go about answering this, I’m thinking it’s active transport ?

[charliemcgee]

Just wondering when you say Glucose phosphate is that the same thing as hexose-1, 6-biphosphate?This is the term our teacher used. Also if that is the case is glucose phosphate fine to use in an exam answer?

[Nghtky]

Ahh thank you for your clarity, the textbook wasn’t so clear!!

[angelumeokaleo]

im so confused with the whole aerobic anaerobic thing on the mark scheme. is glycolysis aerobic or anaerobic ?

[deathstar]

If pyruvate molécules has to be actively transported into the mitochondria is there really a net gain of ATP molecules or is it maybe a net gain gain of one ATP after it’s been actively transported ?

[mehnazparween]

mam you teach very well thank you so much👌

[iacs]

there is one phosphate with each triose phosphate then how 2 ADP are produced by each triose phosphate

[stephanie]

hi miss, could you explain what the adp and nad actually do in glycolysis?

[michaelrowland-ushe]

Is this what happens after eating carbohydrate food

[zeenazeena]

Hi miss estruch thank you for the video, how would u recommend we revise/memorise this

in krebs cycle GP is 3C but in here its 6C, im a bit confused on why theyre different
