CELLULAR RESPIRATION I. Introduction ● Cellular respiration is the process by which cells convert the energy stored in organic molecules into a form that can be used by the cell. It takes place in the mitochondria and is essential for the survival of all living organisms. O BACKGROUND * METABOLIC PATHWAY -USES GLUCOSE to PRODUCE ATP * ATP REQUIRED for MANY REACTIONS IN BODY www GLYCOLYSIS ■ via osmosis.org START: * GLUCOSE, ATP, & NAD+ GLUCOSE PYRUVATE ACETYL-CA CITRIC ACID CYCLE (KREB'S CYCLE) CYTOPLASM of CELL MITOCHONDRIAL MATRIX INNER MITOCHONDRIAL MEMBRANE END: ELECTRON TRANSPORT CHAIN (OXIDATIVE PHOSPHORYLATION) ATP & H₂O * NET 30-32 ATP per GLUCOSE * COSMOSIS II. The Three Stages of Cellular Respiration A. Glycolysis • Glycolysis is the first stage of cellular respiration and takes place in the cytoplasm. It involves the breakdown of a glucose molecule into two pyruvate molecules, releasing a small amount of energy. ● B. The Krebs Cycle ● The Krebs cycle, also known as the citric acid cycle, takes place in the mitochondria. It involves the oxidation of the pyruvate molecules produced in glycolysis, releasing more energy in the form of ATP and CO2. C. Electron Transport Chain ● The electron transport chain is the final stage of cellular respiration and takes place in the inner membrane of the mitochondria. It involves the transfer of electrons from the Krebs cycle to oxygen, producing water and releasing the most energy in the form of ATP. III. The Role of ATP ATP (Adenosine triphosphate) is...

Love this App ❤️, I use it basically all the time whenever I'm studying
Alternative transcript:
the energy currency of the cell and is produced by cellular respiration. • It can be used by the cell to power various processes, such as muscle contraction, ion transport, and synthesis of macromolecules. IV. Anaerobic Respiration • • It produces a smaller amount of ATP than aerobic respiration and results in the production of lactic acid or ethanol. Anaerobic respiration is a type of cellular respiration that takes place in the absence of oxygen. V. Conclusion ● Cellular respiration is a complex process that converts the energy stored in organic molecules into a form that can be used by cells. It takes place in three stages: glycolysis, the Krebs cycle, and the electron transport chain. The end product of cellular respiration is ATP, which powers many cellular processes. ● ● ● Anaerobic respiration is a type of cellular respiration that occurs in the absence of oxygen.
