Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH . [ 2 ]
Chromosomal reciprocal translocation of the 4th and 20th chromosome. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation.
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
The technique involves whole genome amplification from a single cell which is then used in the array CGH method. It may also be used in couples carrying chromosomal translocations such as balanced reciprocal translocations or Robertsonian translocations, which have the potential to cause chromosomal imbalances in their offspring.

The F-type proton ATPase is a multi-subunit enzyme of the F-type (also referred to as ATP synthase or F O F 1 ATPase). It is found in the mitochondrial inner membrane where it functions as a proton transport-driven ATP synthase. In mitochondria, reducing equivalents provided by electron transfer or photosynthesis power this
A single chromosome 18's short arm may be absent entirely or in part, resulting in deletion 18p syndrome. To find out if one parent has the unbalanced 18p- deletion or is a balanced translocation carrier, it is necessary to examine their parental karyotypes.
A 2023 study published in the International Journal of Environmental Research and Public Health found that simply engaging in walking after a carbohydrate-dense meal can help decrease blood sugar ...
The carriers in the electron transport chain use some of the electron's energy to actively transport protons from the stroma to the lumen. During photosynthesis, the lumen becomes acidic, as low as pH 4, compared to pH 8 in the stroma. [30] This represents a 10,000 fold concentration gradient for protons across the thylakoid membrane.
