What is the cell membrane composed of? Which tissue or cell type is not paired with the correct effect? A. epithelial: reabsorption in the kidney tubules B. smooth muscle: vasoconstriction of blood vessels C. connective tissue: secretion of hormones into the blood D. cardiac muscle...
Cell Metabolism Answer The two types of lipids that are part of the cell membrane are phospholipids and sterols. While they are similar to other lipids in that they dissolve readily in organic solvents, what sets these two membrane lipids apart from other lipids is the...
A cell biologist’s view of memory: revisiting the neuron doctrine Kelsey C. Martin Over a century ago, the anatomist Ramon y Cajal used the Golgi staining method to visualize individual cells in the brain. He observed that the brain was composed of discrete cells rather than of a “reticula...
Chlor-alkali plants based on membrane cells have been in operation for more than a decade. With rare exceptions new plants will be based on this relatively recent technology. Over the years you have...doi:10.1007/978-94-009-1137-6_19Donald J. Groszek...
In mammals, telomeres are composed of TTAGGG repeats, which are bound by a protein complex termed shelterin. Cell divisions lead to the progressive erosion of telomeric repeats. When telomeres become too short to recruit the shelterin complex, they become dysfunctional, leading to telomere ...
Lipids are a broad group of organic compounds that play important roles in living organisms, including cell membrane structure and chemical signals, and that are used to store energy. These compounds are typically insoluble in water, termed "hydrophobic," due to the large number of nonpolar bonds...
Firstly, what is an organelle? Organelles are small subcellular structures located in the cytoplasm of eukaryotic and prokaryotic cells, and in more complex eukaryotic cells, organelles are often enclosed by their own membrane. Each organelle performs a specialised function for that cell, much like ...
This is the only part of the sperm cell that enters into the egg cell. As such it is the most important part of the spermatozoon. Its purpose is to fuse with the nucleus of the egg cell and complete the genetic complement of the new being. Plasma membrane Surrounds the acromosome and...
What is a membrane? What type of cell has a membrane-enclosed nucleus and other membrane-enclosed organelles? All organisms except bacteria and archaea are composed of this type of cell. What are the functions of the cell membrane? Name the other two names of the cell membrane. ...
