Osteoporosis is a term that describes the loss of calcium from bones resulting in bones that are thin. Since parathyroid hormone (PTH) removes calcium from bones (that is what it does), all patients with a parathyroid problem will eventually develop thin bones. Bones with osteoporosis due to parathyroid problems can ache and hurt because the PTH is actively destroying the bone. Bones with osteoporosis are fragile bones which are much more susceptible to fractures and breaks.
Answer:
Explanation:
To calculate body fat percentage, add your waist and hip measurements, and then subtract the neck measurement to determine your circumference value. For example, if your waist is 30, your hips are 36, and your neck is 13, your circumference value would be 53.
Answer:
A. True. If the delivery of prospective lysosomal proteins
from the trans Golgi network to the late endosomes
were blocked, lysosomal proteins would be
secreted by the constitutive secretion pathway.
B. False. Lysosomes digest only substances that have been
taken up by cells by endocytosis.
C. False. N-linked sugar chains are found on glycoproteins
that face the cell surface, as well as on
glycoproteins that face the lumen of the ER, trans
Golgi network, and mitochondria.
Explanation:
A. Lysosomal proteins are carried through the indirect constitutive secretion pathway that transports lysosomal proteins from the TGN to plasma membrane and delivers to the late endosomes and the lysosomes.
B. Lysomes digest cellular components and materials by both endocytosis and autolysis.
- Autolysis is a self-destructive pathway by the action of enzymes in the lysosomes.
- Endocytosis is a receptor-mediated pathway and lysosomes digests substances that have been taken up or attached by specific receptors.
- Phagocytosis, an endocytosis pathway, involves ingestion of macromolecules, degraded cellular material, cellular debris, and decayed microbial cells
.
C. N-linked sugar chains are not present on the lumen of the mitochondria because mitochondria does not involve in vesicular transport.
N-linked glycosylation occurs by the action of the enzymes are present in the lumen of ER and golgi cisternae of the TGN and the sugars get attached to the glycoproteins on their lumen.
Answer:
Well yeah but only if you're bad
at taking pills lol
Answer:
The answer is the Pulmonary Artery.
Explanation:
The large vessel found in the front of the heart in front of the aorta is the PULMONARY ARTERY. It is also known as PULMONARY TRUNK. It is responsible for carrying blood from the right ventricle to the lungs to be oxygenated later and then pass to the right heart.
