Maslow's pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level safety needs and then psychological needs become active glucose the form of sugar that circulates in the blood and provides the major source of energy for body tissues. 236 lessons This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Once pathogens are entrapped inside a vesicle, the vesicle will fuse with a lysosome. Two types of active transport are membrane pumps (such as the sodium-potassium pump) and vesicle transport. This means that active transportation, a function in cellular biology, is something that one can observe in everyday occurrences at a cellular level and environment. Carrier proteins are _______ proteins, as they span the length of the cell membrane. For example, active transport is used by the human body to move amino acids from the persons gut allowing specific food to be broken down and absorbed into the body. This is extremely important for action potentials and the passage of glucose from the ileum into the blood, as we will discuss in the next section. One of these micro-processes is called active transport.
