Knowledge and Skills Statement

Science concepts--biological structures, functions, and processes. The student knows that biological structures at multiple levels of organization perform specific functions and processes that affect life.

Applications of the concept of homeostasis include but are not limited to guard cell function in plants,  contractile vacuoles in paramecium, water absorption in roots, nephron reabsorption in the kidneys, muscle contraction, and gas exchange in the alveoli.

the reason for which an object or a process occurs in a system

the process by which cells and organisms maintain internal stability; self-regulating and allows the cell or organism to adjust to changing environmental conditions

a group of atoms that are chemically bonded to each other

a natural phenomenon marked by gradual changes that lead toward a particular result; a continuing natural or biological activity or function

something arranged in a definite pattern of organization; the arrangement of particles or parts in a substance or body; the aggregate of elements of an entity in their relationships to each other

Summary:  Ubiquitylation of membrane proteins has gained considerable interest in recent years. It has been recognized as a signal that negatively regulates the cell surface expression of many plasma membrane proteins both in yeast and in mammalian cells. In this review, we discuss the progress in understanding these processes, achieved during the past several years.

Summary:  This article aims to review what is currently known about the membrane transport systems that mediate the flux of solutes between the intraerythrocytic malaria parasite and the plasma. The major focus is on the most virulent of the malaria parasites infectious to humans, P. falciparum, but with reference made to other parasites and host species where appropriate.
