    • What Is The Difference Between Active Transport and Passive Transport?

    Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.

    Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine tr...

    Antiport Pumps

    Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks. One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”

    Symport Pumps

    Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration. In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient. One example of a symport pump – that of the sodium-glucose transpo...

    Endocytosis

    In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis. In endocytosis, the cell uses proteins in its membrane to fold the membrane into the shape of a pocket. This pocket forms around the contents to be taken into the cell. The pocket grows until it is pinched off, re-forming the cell membrane around it and trapping the pocket and its contents inside the cell. These membrane pockets, which carry...

    Sodium Potassium Pump

    One of the most important active transport proteins in animals is the sodium-potassium pump. As animals, our nervous system functions by maintaining a difference in ion concentrations between the inside and outside of nerve cells. It is this gradient that allows our nerve cells to fire, creating muscle contractions, sensations, and even thoughts. Even our heart muscle relies upon these ion gradients to contract! The ability of the sodium-potassium pump to transport potassium into cells while...

    Sodium-Glucose Transport Protein

    A famous example of a symport pump is that of the sodium-glucose transport protein. This protein binds to two sodium ions, which “want” to move into the cell, and one glucose molecule, which “wants” to stay outside of the cell. It represents an important method of sugar transportin the body, required to provide energy for cellular respiration. The natural diffusion of sodium ions inside the cell facilitates the movement of glucose into the cell. Glucose can be carried into the cell with the s...

    White Blood Cells Destroying Pathogens

    An important exampleof endocytosis is the process by which white blood cells “eat” pathogens. When white blood cells recognize a foreign object inside the body, such as a bacterium, they fold their cell membrane around it to take it into their cytoplasm. They then merge the vesicle containing the invader with a lysosome – a vesicle containing strong chemicals and enzymes that can break down and digest organic matter. They have essentially just created a cellular “stomach” to “digest” the inva...

    Active transport moves substances from a region of lower concentration to a higher concentration, i.e., against the concentration gradient. There is an energy requirement for this process, as it does not occur naturally in the absence of active forces. In contrast, passive transport occurs naturally, as substances move down a concentration gradient...

    • Cells and Organization. Cells are the basic unit of life. The smallest organism consists of one cell. Within that cell is the cellular equivalent of organs, called organelles.
    • Environmental Adaptation. Organisms must be able to adapt to their changing environments. For example, during the season when the sun is directly overhead, plants will grow upward, but they will grow more toward the side during those seasons when the sun is lower in the sky.
    • Homeostasis. Organisms must maintain an internal environment that is conducive to cell metabolism. For example, humans must maintain a specific body temperature.
    • Growth and Development. All organisms undergo a process of growth and development. Single-celled organisms start as smaller cells that grow. The contents of the cell may become more diverse and complex.

  4. List the properties of life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

  5. Natural selection postulates that individuals with traits that are most beneficial in their environment reproduce more prolifically, and this leads to that trait becoming more common in the population in the next generation. This increase in frequency of a trait is evolutionary change.
