    Cell Signaling

    6.1 : What is Cell Signaling?02:03

    6.1 : What is Cell Signaling?

    Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. ...

    6.2 : Bacterial Signaling01:30

    6.2 : Bacterial Signaling

    Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. ...

    6.3 : Yeast Signaling01:28

    6.3 : Yeast Signaling

    Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in ...

    6.4 : Contact-dependent Signaling01:19

    6.4 : Contact-dependent Signaling

    Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through ...

    6.5 : Autocrine Signaling01:01

    6.5 : Autocrine Signaling

    Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this ...

    6.6 : Paracrine Signaling01:21

    6.6 : Paracrine Signaling

    Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a ...

    6.7 : Synaptic Signaling01:12

    6.7 : Synaptic Signaling

    Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be ...

    6.8 : G-protein Coupled Receptors01:21

    6.8 : G-protein Coupled Receptors

    G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that ...

    6.9 : Internal Receptors01:31

    6.9 : Internal Receptors

    Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross ...

    6.10 : Endocrine Signaling01:45

    6.10 : Endocrine Signaling

    Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the ...

    6.11 : What are Second Messengers?01:12

    6.11 : What are Second Messengers?

    Because many receptor binding ligands are hydrophilic, they do not cross the cell membrane and thus their message must be relayed to a second messenger on ...

    6.12 : Intracellular Signaling Cascades01:24

    6.12 : Intracellular Signaling Cascades

    Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is ...

    6.13 : Ion Channels01:19

    6.13 : Ion Channels

    The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. ...

    6.14 : Enzyme-linked Receptors01:00

    6.14 : Enzyme-linked Receptors

    Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors ...
