deficit in Biological Definition

Photosynthesis

... The NADPH is the main reducing agent in cells, providing a source of energetic electrons to other reactions. This leaves chlorophyll with a deficit of electrons, which must be obtained from some other reducing agent. In plants and algae this role is played by water, resulting in the production ...

Light-dependent reaction

... a photon is absorbed by the chlorophyll core of photosystem II, exciting two electrons which are transferred to the primary acceptor protein. The deficit of electrons is made up for by taking electrons from a molecule of water, splitting it into O 2 and H + . The electrons transfer from the primary ...

Vitamin

... blood coagulation . Vitamin deficiency and excess An organism can survive for some time without vitamins, although prolonged vitamin deficit results in a disease state, often painful and potentially deadly. Body stores for different vitamins can vary widely; an adult may be deficient in ...
