ATP & Respiration: Crash Course Biology #7
CrashCourse・2 minutes read
Cells produce energy through cellular respiration, converting glucose into ATP through stages like glycolysis and the Krebs Cycle, ultimately generating around 38 ATPs per glucose molecule.
Insights
- Glucose is converted into energy through cellular respiration, a process requiring oxygen and involving ATP production in three stages: glycolysis, the Krebs Cycle, and the electron transport chain.
- ATP, known as the "currency" of biological energy, is crucial for cell functions and is generated through the removal of a phosphate group, with NADH and FADH2 playing essential roles in producing ATP via the electron transport chain.

Recent questions
What is cellular respiration?
Cellular respiration is the process by which cells convert glucose into energy, utilizing oxygen and producing CO2, water, and ATP in the mitochondria.
What is the primary source of energy in cells?
Glucose, with the chemical formula [C6H12O6], is the primary source of energy in cells, undergoing cellular respiration to produce ATP.
What is ATP and its role in cells?
ATP, or adenosine triphosphate, is the energy currency of biological systems, essential for cellular functions and created through the removal of a phosphate group, releasing energy for cellular processes.
What are the three stages of cellular respiration?
Cellular respiration involves three stages: glycolysis, the Krebs Cycle, and the electron transport chain, each contributing to the production of ATP from glucose.
How is ATP generated in the electron transport chain?
The electron transport chain utilizes electrons from NADH and FADH2 to create a proton gradient, driving ATP synthase to produce ATP by combining ADP and phosphates, generating a total of around 34 ATPs from a single glucose molecule in animal cells.
