When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.
Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.
Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems <u>one </u>and <u>three</u>, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.

Answer:
The cell
Explanation:
<em>The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is </em><em>the cell.</em>
This is in accordance with the cell theory which has three basic components, including:
1. The cell is the basic unit of life
2. All living organisms are made up cells
3. Cells arose from pre-exsiting cells.
<u>Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.</u>

Insulin causes blood glucose levels to drop, which signals the pancreas to stop producing insulin in a negative feedback loop. Hormonal stimuli refer to the release of a hormone in response to another hormone. A number of endocrine glands release hormones when stimulated by hormones released by other endocrine organs.
