MCAT-11-biology Flashcards
What are erythrocytes
erythrocytes, or Red Blood Cells, don’t contain DNA
Trypsin
Trypsin is a digestive enzyme, released from the pancreas into the duodenum (first part of the small intestine), Its optimal pH is ~8. Trypsine =inTestines
Pepsin
Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides. Pepsin=peptobismo
Melanocytes
Melanin producing cells located in the skins bottom layer of the epidermis.
Microfilaments
Microfilaments or actin filaments are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of eukaryotic cells.
Actin
Actin is a globular multi-functional protein that forms microfilaments. It is found in essentially all eukaryotic cells
Myosin
Myosins comprise a family of ATP-dependent motor proteins and are best known for their role in muscle contraction and their involvement in a wide range of other eukaryotic motility processes.
Tubulin
Tubulin is the protein that polymerizes into long chains or filaments that form microtubules, hollow fibers which serve as a skeletal system for living cells. Microtubules have the ability to shift through various formations which is what enables a cell to undergo mitosis or to regulate intracellular transport.
Bowman’s capsule.
is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine.
Deuterium
^2H
Atrium
Blood enters the heart via the atrium, into the left atrium from the lungs and the right atrium from the body
Ventricle
The blood leaves the heart via the ventricle.
What is a heterocyclic amine?
A heterocyclic compound has a ring that contains elements other than carbon in the ring.
What is a primary amine?
Primary amines are formed when exactly one of the hydrogens in ammonia is replaced by an alkyl group.
Which AA causes turns
proline
