(chiefly, Glut4) located inside the cytoplasmic vesicles in the intracellular pool. The vesicles rapidly fuse into the plasma membrane where the GluTs become inserted. When the insulin stimulus is terminated, these GluTs are recycled back into the vesicles in the intracellular pool for the next ...
a small structure within the ovary of the flower. The ovary is a larger structure within the flower that contains and protects usually many ovules. Flowering plants are unique in that their ovules are entirely enclosed in the ovary. The ovary itself is part...
The two types of punishment used in psychology include: Positive punishment: a consequence whereby a stimulus or factor is added to discourage behaviors, such as criticism or scolding, spanking, doing extra chores, or writing a phrase repeatedly on a piece of paper. Negative punishment: a ...
Several cell types in biofluidic vessels, such as endothelial cells and immune cells, are constantly exposed to shear stress in vivo. This mechanical stimulus has a great impact on the physiological behavior and adhesion properties of cells, and should be taken into account when performing respectiv...
