For businesses and institutions — AI harness and API inquiriesHere are this week's slides. What are they about, in one line?
A 40-page lecture on cellular respiration, how cells break down glucose for energy (ATP), in the order glycolysis → citric acid cycle → electron transport chain.
Sum up just the key points for the exam
Cellular respiration: key points
- 1.Glycolysis · In the cytoplasm, 1 glucose → 2 pyruvate, net 2 ATP
- 2.Citric acid cycle · In the mitochondrial matrix; releases CO₂, makes NADH and FADH₂
- 3.Electron transport chain · Inner mitochondrial membrane; O₂ is the final electron acceptor · most ATP
For the exam, memorize each stage with its location and products.
Key features, shown on real screens
With the AI chatbot at the center, use the lecture-note, voice and comic tools from one account.Text shown in the screens is an example to help explain each feature.

CHAPTER 3
The 3 stages of cellular respiration
Glycolysis
Cytoplasm
Citric acid cycle
Mitochondrial matrix
Electron transport
Inner mitochondrial membrane
Selection- • Without oxygen, ATP comes from fermentation after glycolysis
- • Most ATP is made in the electron transport chain (oxidative phosphorylation)
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
