gain in Biological Definition

Cellular respiration

... of pyruvate, with the production of another two ATP molecules (for a net gain of 2 ATP). Breakdown of pyruvate There are now two ways to break ... synthase, as well as carbon dioxide and water . This makes for a total gain of 38 ATP molecules during cellular respiration under optimal conditions; ...

Albinism

... is possible on the ocular muscles, effectively simulating (to a limited degree) the improvements in the albino's vision that often come with age, the gain is generally thought be out-weighed by the trauma. The lack of pigment in the eye generally leads to ocular photophobia or hyper-photo-sensitivity ....

Brain

... nervous systems are distinguished by encephalization and bilateral symmetry . Encephalization refers to the tendency for more complex organisms to gain a larger-size through evolutionary time. Larger vertebrates develop a complex of layered, networked and convoluted grey matter and white matter . ...

Chromosome

... , may be lethal or give rise to genetic disorders. Genetic counseling is offered for families that may carry a chromosome rearrangement. The gain or loss of chromosome material can lead to a variety of genetic disorders . Examples include: Cri du chat syndrome , which is caused by the ...

Edward's syndrome

... Edward's Syndrome child during pregnancy or the neonatal period . Some children with Edward's Syndrome develop only a small degree, while others gain many of the skills of their Down's Syndrome peers - walking, talking, attending school, holding down a job, etc. As major medical interventions are ...

Leaf

... Spruce ( Picea abies ) are needle-shaped and the arrangement is spiral Leaves are set in a particular arrangement around the stem in order to gain an optimal yield of light. Subsequent leaves are arranged in spirals, clockwise or counterclockwise, with always the same angle of divergence . ...

Osmoregulation

... can either be active or passive. An example are marine fish. By drinking in sea water, and actively excreting salt out from the gills, the fish will gain salt as it produces an isotonic urine. Osmoregulators tightly regulate their body osmolarity which always stays constant and are more common in ...

Patau syndrome

... in cell division called nondisjunction can result in reproductive cells with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 13. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have an ...

Photosystem

... numerous antenna pigments and proteins. Because chlorophyll a can only absorb light of a narrow wavelength , it works with the antenna pigments to gain energy from a larger part of the spectrum. The pigments absorb light of various wavelengths and pass along their gained energy to the reaction ...
