Post Mock Proteins Flashcards
Antibody
The flexible arms of antibodies protect the body from disease by recognising and binding to foreign molecules (more than one at once) and thus preventing the viral RNA or DNA to enter the cell. The immune system produces specific anitbodies for specific pathogens; when an anitbody identifies a pathogen it then signals to the immune system to destroy it.
Collagen
Forms a strong triple helix that is used throughout the body for structural support, collagen fibrils and then aggregate to form collagen fibres.
Collagen is the most abundant protein in your body, accounting for about one-third of its protein composition. It’s one of the major building blocks of bones, skin, muscles, tendons, and ligaments. Collagen is also found in many other body parts, including blood vessels, corneas, and teeth.
Calcium Pump
The calcium pump (with magnesium and powered by ATP) moves ions across cell membranes allowing synchronised contraction of muscle cells. Hydrophobic proteins are within the membrane with the lipids whilst hydrophilic parts of the chain are on the outside of the membrane.
With each contraction cycle, actin moves relative to myosin. The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin.
Isulin hormone
Small, stable two-chain globular protein that can easily maintain its shape while travelling through the blood to regulate blood sugar levels. Quarternary structure (dimmer).
Globular proteins are spherical in shape and usually water soluble. Examples of globular proteins include haemoglobin, insulin and many enzymes in the body.
Amalayse
An enzyme with a catalytic site that being the breakdown of carbohydrate polysaccharide starch in saliva.
Ferritin
Spherical storage protein with pores that allows iron to enter and exit. Form a hollow shell that stores iron from blood in a non-toxic form.
Ferritin, an iron storage protein, is the primary iron storage mechanism and is critical to iron homeostasis. Ferritin makes iron available for critical cellular processes while protecting lipids, DNA, and proteins from the potentially toxic effects of iron.
