University of Seville Researchers from the Department of Pharmacology at the University of Seville have recently published a study in which they state that diets supplemented with aqueous extract of Annona muricata L. leaves can prevent the symptoms associated with fibromyalgia, so improving the lives of these patients. Leaves of the species Annona muricata L. come from a tree of between 4 and 6 metres in height, from the botanical family Annonacese. They are simple leaves, oblong and egg like or oblong and elliptical in shape and between 5 and 15 cm in length. This species is native to the tropical areas of the Americas and is especially abundant in the Amazon region. It is usually cultivated for its medicinal use. The leaves have different ethnomedical uses according to their country of origin. The most important uses in traditional medicine, scientifically validated in pre-clinical tests, are for inflammation, pain, infections, diabetes and cancer. "The consumption of extract of…
You are culturing 2 algal species. Species A has a maximum photosynthetic output of 8 mg C mg-1 chl a h-1 and a half saturation constant of 20 µE m-2 s-1. Species B reaches a maximum photosynthetic output of 4 mg C mg-1 chl a h-1 and has half saturation constant of 18 µE m-2 s-1. Which species will be growing faster at a PAR light intensity of 80 µE m-2 s-1? Why?
Scientists uncover a new pathway for synthesis of Threonine (see below). They also identify mutants that cannot grow on media lacking threonine (Thr-1, 2 and 3). These mutants have mutations in separate enzymes in this pathway. They are able to grow when different supplements are added to the media (see below). Based on this, what is the order of the enzymes in this pathway? a. Thr-2, 1, 3 b. Thr-2, 3, 1 c. Thr-1, 2, 3 d. Thr-3, 2, 1
In conditions of dehydration, plant cells can increase their water retention by regulating the function of some or all of their aquaporins, membrane-bound protein channels that allow water to move through the cell membrane via facilitated diffusion. Which of the following describes a likely mechanism by which aquaporins can be used to regulate the movement of water across the plant cell membrane? A B с D Synthesis of additional aquaporins by the plant cell ribosomes will allow the cell to coun- teract the movement of water out of the cell. Inhibition of ATP hydrolysis will make the aquaporins unable to remove water from the cell and cause more water to remain in the cell. Inactivation of aquaporins will make water molecules unable to move across the plant cell membrane and allow more water to remain in the cell. Inhibition of the plant cell Golgi apparatus will decrease the production rate of vesicles and slow down the exocytosis of water molecules.
