What does carbon fixation mean biology?
Carbon fixation. (Science: plant biology) The process by which photosynthetic organisms such as plants turn inorganic carbon (usually carbon dioxide) into organic compounds (us. Carbohydrates).
What is fixation in medical term?

What is fixation give example?
The definition of a fixation is a point of focus, an obsession or the chemical reduction into a solid form. An example of a fixation is a compulsion to bite one’s nails.
What is an example of carbon fixation?
In photosynthesis, energy from sunlight drives the carbon fixation pathway. Oxygenic photosynthesis is used by the primary producers—plants, algae, and cyanobacteria. They contain the pigment chlorophyll, and use the Calvin cycle to fix carbon autotrophically.
What happens during carbon fixation?
Carbon fixation is the process by which inorganic carbon is added to an organic molecule. Three molecules of CO2 along with ATP, NADPH, and water are needed for a full turn of the cycle and the production of a glyceraldehyde 3-phosphate (Ga-3P) molecule for use by the cell in making starch or sugar.
What is fixation and explain?
In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues’ mechanical strength or stability.
What is fixation in reading?
In simple terms, eye fixation refers to the point where your eyes take a rest during the reading process. People who tend to make fewer eye fixations during reading usually have a higher reading pace than people who make more frequent fixations.

What is an example fixation?
Even the most careful fixation does alter the sample and introduce artifacts that can interfere with interpretation of cellular ultrastructure. A prominent example is the bacterial mesosome , which was thought to be an organelle in gram-positive bacteria in the 1970s, but was later shown by new techniques developed for electron microscopy to be simply an artifact of chemical fixation.
What is an example of fixation in psychology?
These fixations occur when an issue or conflict in a psychosexual stage remains unresolved, leaving the individual focused on this stage and unable to move onto the next. For example, individuals with oral fixations may have problems with drinking, smoking, eating, or nail-biting .
