Cellular respiration

1. The molecule produced from glycolysis that enters the mitochondria for further energy production.
4. An element that forms the backbone of organic molecules, including glucose.
6. A series of chemical reactions that regenerate molecules for continuous processes.
7. The sum of all chemical reactions in an organism, including cellular respiration.
10. The process that allows ATP production in the absence of oxygen by converting pyruvate.
12. A compound produced during anaerobic respiration that can cause muscle fatigue.
13. A type of fermentation that occurs in muscle cells and produces lactic acid.
15. The first step of cellular respiration that breaks down glucose into pyruvate.
16. A cycle in cellular respiration that generates high-energy molecules for the electron transport chain.
17. The main energy carrier molecule produced during cellular respiration.

2. A negatively charged particle involved in energy transfer in the electron transport chain.
3. A simple sugar that serves as the main energy source for cellular respiration.
5. A gas required for aerobic cellular respiration to produce ATP.
8. A type of respiration that requires oxygen to produce ATP.
9. The organelle where most of cellular respiration takes place.
11. The ability to do work, released during cellular respiration in the form of ATP.
14. A type of respiration that does not require oxygen and produces less ATP.
