Ribosomes are made up of two subunits?
Yes, ribosomes are composed of two subunits: a large subunit and a small subunit. These subunits come together during protein synthesis to translate messenger RNA into proteins.
What are five example of proteins?
Hemoglobin: A protein responsible for carrying oxygen in red blood cells. Insulin: A hormone protein that regulates blood sugar levels. Collagen: A structural protein that provides strength and elasticity to skin, tendons, and ligaments. Enzymes: Proteins that catalyze biochemical reactions in the body. Antibodies: Proteins produced by the immune system to help defend against pathogens.
Why proteins made by free ribosomes free of carbohydrates?
Proteins made by free ribosomes are not inherently free of carbohydrates. Ribosomes produce proteins based on genetic instructions, and these proteins can be modified with carbohydrates after translation. The addition of carbohydrates to proteins is a process called glycosylation, which can occur in the endoplasmic reticulum or Golgi apparatus after the protein is synthesized by ribosomes.
Describe the contents of blood plasma and its role in the human body?
Blood plasma is a yellowish liquid component of blood that carries various cells, proteins, electrolytes, hormones, and waste products throughout the body. Its roles include transporting nutrients, hormones, and waste products, maintaining osmotic balance, and helping with blood clotting. Plasma also plays a crucial role in the immune response and carrying antibodies to fight infections.
Enzymes are examples of which of these molecule groups?
Enzymes can be classified as either simple enzymes or complex enzymes. 1) Simple enzymes are predominantly made up of proteins. 2) Complex enzymes are enzymes that require cofactors like iron or zinc ions to function properly.
Notes on blood plasma?
blood is separated into 2 things. the blood cells, and the plasma. The plasma is about 55 percent of the blood and in that 55 percent, 90 percent of it is water, and other 10 percent is dissolved gases, salts, nutrients, enzymes, hormones, waste products, and proteins called plasma proteins.
2 substances that don't pass out of blood?
Red blood cells and large proteins are two substances that typically do not readily pass out of the blood vessels into surrounding tissues.
What 2 things are they made of?
They are primarily made of water and organic compounds like proteins, lipids, carbohydrates, and nucleic acids.
Circulatory system in which blood is contained in vessels?
Yes. Blood is made up of 45% formed elements: 1. Red Blood Cells, 2. White blood cells, and 3. Platelets. Plus 55% plasma which is mostly liquid with some plasma proteins and clotting factors.
What are 2 important proteins in human body?
Hemoglobin is a protein that carries oxygen in red blood cells, while insulin is a protein that regulates blood sugar levels. Both proteins play crucial roles in maintaining proper body function.
What is a cell made of (blood cell)?
a blood cell is made up simply of oxygen and blood. happy 2 help pretty-zebra xxx
What four properties of blood affect the esr?
The four properties of blood that affect the ESR (erythrocyte sedimentation rate) are the concentration of fibrinogen, the size and shape of red blood cells, the presence of inflammatory proteins, and the presence of abnormal proteins like sickle cells or spherocytes. These properties can impact the rate at which red blood cells settle in a tube, affecting the ESR measurement.
Do proteins make up the largest proteins?
Yes some proteins complexes do form quaternary structure. Hemoglobin is a classical example for making four subunits to conduct O2 and CO2 transport. It is made up of 2 alpha and 2 beta subunits.Membrane proteins in the nucleus such as nup358 are the largest protein complexes weight above 300kDa.
What is the difference between blood plasma and interstitial fluid in terms of composition?
Blood plasma contains proteins, electrolytes, hormones, and waste products, while interstitial fluid is similar but lacks proteins. Blood plasma is found within blood vessels, while interstitial fluid surrounds and bathes cells in tissues. The movement of substances between blood plasma and interstitial fluid is regulated by capillaries.
How is your blood type determaned?
There are two important blood types: the ABO blood type and the Rhesus blood type. ABO is the A, B, AB, or O blood type, and the Rhesus type is the + or - usually written after the ABO blood type (eg. AB+ or O-). At the level of your blood, blood type is determined by proteins present on the surface of red blood cells, which circulate around your body delivering oxygen to cells. On the surface of red blood cells is a combination of three surface proteins: A, B, and Rhesus. Blood types code for the presence or absence of these proteins. Blood type A have A type surface proteins but lack B. Blood type B lacks A but has B proteins. Blood type AB has both, and Blood type O has neither A nor B. Rhesus positive exhibit the Rhesus protein, while Rhesus negative lack it. It is these proteins which determine which types of blood you can receive safely. Individuals with A type blood cells cannot be exposed to B type surface proteins safely, so B and AB blood is off the cards for them. O negative blood lacks any of these proteins so can be transfused into any patient, hence the term "universal donor". It is your genes which determine which of these proteins are expressed. As with the majority of genes you have two copies of both the ABO and Rhesus genes, one copy from your mother and one from your father. From each parent you inherent either an A, a B, or an O gene, and also either a Rhesus positive (Rh+) or a Rhesus negative (Rh-) gene. The combination of the two genes you have determines your blood type as follows: AA or AO = A Blood type BB or BO = B Blood type AB = AB blood type OO = O Blood type Rh+Rh+ or Rh+Rh- = Rhesus positive Rh-Rh- = Rhesus negative
The movement of fluid into Bowman's capsule is opposed by?
The movement of materials into Bowman's capsule is opposed by two forces.1) Capsule pressure (CP) produced by the walls of Bowman's capsule and fluid alreadyinside the capsule.2) Colloid osmotic pressure (COP) results from the proteins in the blood. Because most proteins do not pass from the blood into the filtrate, the blood is more concentrated than the filtrate. Therefore water tends to move from the capsule back into the blood.
What is one consequence of defective cytoskeletal proteins in red blood cells?
One consequence of defective cytoskeletal proteins in red blood cells is decreased cell flexibility, leading to increased fragility and susceptibility to hemolysis (breakdown). This can result in conditions such as hereditary spherocytosis, where affected individuals have spherical-shaped red blood cells that are less deformable and are destroyed more easily in the spleen.
