You are an amino acid in the lumen of the small intestine of a newborn mammal. You are looking at intestinal epithelial cells that bring important maternal proteins (immunoglobulins) across their apical surfaces by receptor-mediated endocytosis. Your ambition is to be part of a receptor that does that job. A. beginning from the challenge of entering the cell‚ until you have been loaded onto an appropriate tRNA. Amino acids are the building blocks of protein. Within the small intestine

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

1. The advantages of using an electron microscope is that it has a greater magnification‚ so you can see more detail about the organism. It would be preferable to use a light microscope when you want to see the cell in the act of moving or dividing. 2. Prokaryotic cells don’t have organelles like eukaryotic cells do. Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although

Neuroscience: Neurotransmitters (small molecule and neuroactive)‚ storage release removal and disease. 1. The brain is made up of neurons that process and transmit information by electrochemical signaling. Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of
Premium Neuron Nervous system Action potential
Synapses are an essential and fascinating part of communication within the central nervous system. They are the transmitters of chemical and electrical messages that cause us to see‚ feel‚ move and much more. The brain consists of around 100 billion neurons‚ each of which has around 7‚000 synaptic connections to other neurons. It has been estimated that a three year old child has 1‚000 trillion synapses‚ and since number of synapses decreases with age until it stabilises in adulthood it is estimated
