The diaphragm separates the thoracic cavity from the inferior abdominopelvic cavity by forming the thoracic cavity's floor.
The citric acid cycle includes:
Explanation:
The citric acid cycle integrates glucose, fat, and protein metabolism. The cycle's processes are carried out by eight enzymes, which totally oxidize acetate (a two-carbon molecule) in the form of acetyl-CoA into two carbon dioxide and water molecules apiece.
How do living organisms use oxygen?
Explanation:
Oxygen assists organisms in growing, reproducing, and converting food into energy. Humans receive oxygen by breathing into their lungs through their nose and mouth. Our cells use oxygen to break down food and obtain the energy we require to exist.
Lipids are produced in:
Explanation:
The endoplasmic reticulum (ER) produces structural lipids, which are then actively transferred to the membranes of other organelles.
A decomposition reaction can be represented as:
Explanation:
AB-->A+Bis a common symbol for a decomposition reaction, where AB is the substrate and A and B are the products.
