Energy and Metabolism | Biology I
The reaction that harvests the energy of a sugar molecule in cells requiring oxygen to survive can be summarized by the reverse reaction to photosynthesis. In this reaction, oxygen is consumed and carbon dioxide is released as a waste product. The reaction is summarized as: C 6 H 12 O 6 +6O 2 →6H 2 O+6CO 2.
يتعلم أكثرCell parts and functions (article) | Khan Academy
Key points: All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell''s cytoplasm, which is a jelly-like substance containing the cell''s parts. Cells contain parts called organelles. Each organelle carries out a specific function in the cell.
يتعلم أكثرLipid Metabolism in Plants
Introduction. Plant lipids are diverse and essential for cells. They are essential for the integrity of cells and organelles by acting as a hydrophobic barrier for the membrane. In addition, lipids are stored in the form of chemical energy in seeds. Furthermore, they act as a signal molecule to regulate cell metabolism [ 1, 2 ].
يتعلم أكثرCytoplasm: Function and Facts | Sciencing
Cytoplasm is a clear substance that is gel-like in the cell membrane but is on the outside of the nucleus. It contains mostly water with the addition of enzymes, organelles, salts and organic molecules. Cytoplasm will liquefy when it is stirred or agitated. It is often referred to as cytosol, meaning "substance of the cell."
