The peroxisome of plant cells is polarised when fighting fungal penetration. Infection causes a glucosinolate molecule to play an antifungal role to be made and delivered to the outside of the cell through the action of the peroxisomal proteins (PEN2 and PEN3). [22] Peroxisomes in mammals and humans also contribute to anti-viral defense.
The peroxisome is an organelle in the cell similar to the lysosome that functions to detoxify the cell. Peroxisomes contain many different enzymes, such as catalase, and their main function is to neutralize free radicals and detoxify drugs. For this reason peroxisomes are ubiquitous in the liver and kidney.
Physiographic Map from "Geography of Ohio," published in 1923. During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a portmanteau of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline.
Peroxisomal disorders represent a class of medical conditions caused by defects in peroxisome functions. [1] This may be due to defects in single enzymes [2] important for peroxisome function or in peroxins, proteins encoded by PEX genes that are critical for normal peroxisome assembly and biogenesis.
Peroxisomal acyl-coenzyme A oxidase 1 is an enzyme that in humans is encoded by the ACOX1 gene. [5] [6]The protein encoded by this gene is the first enzyme of the fatty acid beta-oxidation pathway, which catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs.
Some of the language used was a tad heavy on the jargon, particularly the section on the genetics of peroxisomes. I feel that the section on the history and evolution of the peroxisome was a little sparse, as well as the medical condition that having a peroxisome disorder can cause and the genetics of peroxisomes could have used more information.
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.
