What structures in the cell membrane function as ion channels? What is one function of the smooth endoplasmic reticulum? What does a cell do, and how do its features help it function? What function does the cell wall perform in a plant?
A simple diagram comparing an animal cell and plant leaf cell by domdomegg / CC BY (https://creativecommons.org/licenses/by/4.0) Essentially, a cell membrane is the outermost barrier that separates the internal contents of a cell in the cytoplasm from the external environment (e.g. ...
The cell membrane – also called the plasma membrane or cytoplasmic membrane – is among the most fascinating and elegant constructs in the world of biology. The cell is considered the fundamental unit or "building block" of all living things on Earth; your own body has trillions of them, an...
Life as we know it depends on barriers, both macro and micro. We are a collection of cells and their outputs. Cells are individual units of life that have a cell membrane that maintains cellular integrity and function. We are as healthy – and only as healthy – as our collective cell m...

In addition to a nucleus, some of the other important organelles of palisade cells include a cell membrane, a large vacuole, chloroplasts as well as a cell membrane among a few others. Between the cells (palisade cells are generally arranged in a vertical manner to each other beneath the epi...

Chemical probes are selective small-molecule modulators, usually inhibitors, of their target protein’s function, that can be used in cell or even animal studies to interrogate the functions of their target proteins. Cheryl Arrowsmith, the leader of a new initiative called Target 2035, which seeks...
This leads to membrane depolarization which activates voltage-gated calcium channels and an increase in calcium influx into the cell. The high intracellular calcium ions result in exocytosis of the secretory granule containing insulin and C-peptide.3 Table 2. Factors influencing insulin secretion ...
