The inability to achieve and maintain an erection is called Impotence or erectile dysfunction whilst a person who has low sperm count with the inability that to achieve a successful pregnancy or physical inability to ejaculate semen from the body is called infertility.
The light-independent reaction for obtaining energy (I think this is what you are talking about) occurs within the organism. This is because cellular respiration does not require light, seeing as how most humans do not need light directly (although they need the Sun for photosynthesis to occur in plants so that the plants produce Oxygen) in order to survive. Hopefully this helps!
When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.
- It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
- An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
- An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
- Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

The dialysis tubing and cell membrane are similar in the fact they protect the cell. The tubing as well as cellmembranes are selectively permeable, they control the movement of substances in and out of the cell. Starch molecules are larger than glucose molecules.
