i learnt more stuff in 4 mins watching this video Then a week in school!!

Notes for this video Cellular respiration is an exothermic reaction essential for releasing energy stored in glucose molecules, which are primarily produced by plants during photosynthesis. This process continuously occurs in living cells and involves breaking down glucose to transfer its trapped energy. Importantly, this does not create new energy but redistributes the existing one from glucose. Energy use 00:00:58 Organisms use energy for building larger molecules, muscular contraction, and maintaining body temperature. Energy is essential for numerous cellular reactions catalyzed by enzymes; collectively, these processes are termed metabolism. Metabolism encompasses all chemical activities necessary to sustain life. Aerobic respiration occurs when oxygen is available and efficiently transfers energy from glucose in plants and animals within mitochondria. Its equation-glucose plus oxygen forming carbon dioxide plus water-is the reverse of photosynthesis. Anaerobic respiration 00:03:01 Anaerobic respiration occurs without oxygen, typically during intense activities like sprinting when the body cannot supply enough oxygen for aerobic respiration. The process converts glucose into lactic acid but is less efficient due to incomplete glucose breakdown, as no oxygen is available to fully oxidize it. This inefficiency means not all energy from glucose is utilized. Additionally, lactic acid accumulation poses a problem since it must be removed later. Fermentation 00:03:50 In anaerobic respiration within yeast, glucose is converted into ethanol and carbon dioxide instead of lactic acid. This process, known as fermentation, has significant industrial uses. In bread-making, the carbon dioxide produced by yeast creates air pockets that make bread light and fluffy. Additionally, fermentation's production of ethanol enables its use in creating alcoholic beverages like beer and wine.

Whoops, sorry Cognito, the accidental dislike was my fault, your videos are excellent and I removed the dislike and liked the amazing video. Sorry (for the accidental dislike), once again, your videos are amazing and I've recommended you to my science teacher. Keep up the brilliant work, and congrats on 200k+ subs!

[@zainali8979]

Very informative 👍

[@coldchickennoodles5575]

Is this respiration in humans or plants? because in 0:18 you said "originally made in photosynthesis" I'm confused

[@icarussoph]

Aerobic respiration occurs in both, but i think he meant that the glucose us humans use for aerobic respiration is made by photosynthesis, as we get our glucose from the food we eat, our body doesn't create it- and all biomass comes from plants as they're producers so yeah (i don't know if I'm 100% correct)

[@blazespooky]

Glucose is a product of plants...they are the first ones who are mking them😊

[@omaraburizaizah7098]

do both anaerobic respiration and aerobic respiration give out heat?

[@duckyy-.]

Both processes are not 100% efficient, which means that some energy will be released in the form of heat. hope that answers your question after 2 years XD

it's basically all the chemical processes in your body, especially those that cause food to be used for energy and growth. for example, if you have a faster metabolism, then you'll burn fat quicker.
