What organisms can survive without sunlight?
What organisms can survive without sunlight?
There are bacteria that live in hot springs and other volcanic water that get their energy from chemicals released as a result of volcanic activity. They do not need light, and they do not need oxygen, and the Earth’s interior provides them with heat, so they can live without the sun.
Can some organisms survive without energy from the sun?
Can some organisms survive without energy from the sun? Yes, some deep-sea ecosystems do not depend on the sun for their energy source. Primary producers can harness chemical energy from inorganic molecules such as hydrogen sulfide to produce carbohydrates through chemosynthesis.
How is ADP and ATP related?
Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. When it’s fully charged, it’s ATP. When it’s run down, it’s ADP.
Is a process by which some organisms use chemical energy instead of light energy to make energy storing carbon based molecules?
A process by which organisms use chemical energy instead of light energy to make energy-storing carbon-based molecules. produces molecules that carry energy to the second part of cellular respiration. Chloroplast. absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water.
What provides the largest number of ATP per molecule?
SC CH 4

| The breakdown of which of the following provides the largest number of ATP per molecule? | lipids |
What would happen without Rubisco?
Rubisco is found in plants and is used during photosynthesis. Without this enzyme, plants couldn’t synthesize glucose and produce oxygen from CO2, water, and sunlight. Without plants other organisms wouldn’t be able to exist.
Where can Rubisco be found?
Form I Rubisco, found in green algae and vascular plants, is a hexadecamer composed of 8 large subunits (RbcL), encoded by the chloroplast genome and 8 small, nuclear-encoded subunits (RbcS). Unlike its cyanobacterial homolog, which can be reconstituted in vitro or in E.
