Oxygen Cycle Autotrophs: Release O2 into atmosphere via photosynthesis All life: Absorbs O2 to be used during cellular respiration Respiration: creates ATP energy for cells Carbon Cycle CO2 CO2 Carbon = (organic molecules) carbohydrates, proteins, lipids, nucleic acids Plants & autotrophs: Intake:...
Heterotrophs acquire the high-energy carbon compounds from the autotrophs by consuming them, and breaking them down by respiration to obtain cellular energy, such as ATP. The most efficient type of respiration, aerobic respiration, requires oxygen obtained from the atmosphere or dissolved in water....

Muscles of Respiration Understanding the Mechanism of Breathing Lesson Summary Frequently Asked Questions What is the relationship between inspiration and expiration? Breathing involves both inspiration and expiration. Inspiration refers to a person inhaling air into their lungs to provide the body with ox...
This might explain why the retrospective cycles of intermediary metabolism offer no metaphor as vivid as the "metabolic wheel" in Fritz Lipmann's 1941 review of the generation and transfer of energy through phosphate bonds, those irreversible pace- maker reactions of cellular physiology (Fig. 9b...
What organisms can perform photosynthesis and cellular respiration? What role does oxygen play in the Krebs cycle? How are proteins catabolized into the Krebs cycle? What part of the cell cycle is the longest? What is the molecule that leaves the Calvin cycle to be converted into glucose?
How is Cell Respiration used the Carbon Cycle? Cellular Respiration releases CO2 back into the atmosphere by breaking down glucose for energy How have humans caused a large increase of CO2 in the atmosphere and contributed to global warming? Burning fossil fuels and deforestation What is the Greenh...

and adenosine triphosphate (ATP). ATP is a high energy molecule produced by the processes of cellular respiration and fermentation. In the phosphorus cycle, phosphorus is circulated mainly through soil, rocks, water, and living organisms. Phosphorus is found organically in the form of the phosphate...
