Endosymbiotic theory and endoplasmic reticulumThe endosymbiotic theory is a scientific theory that explains the evolution of eukaryotic cells from prokaryotic cells through a process of endosymbiosis. It proposes that mitochondria and chloroplasts, two membrane-bound organelles found in eukaryotic cells, originated as free-living bacteria that were engulfed by ancestral eukaryotic cells.
The endoplasmic reticulum (ER) is a complex network of flattened sacs and tubules that extends throughout the cytoplasm of eukaryotic cells. It plays a key role in protein and lipid synthesis, folding, and transport. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (RER), which is studded with ribosomes and involved in protein synthesis, and smooth endoplasmic reticulum (SER), which lacks ribosomes and is involved in lipid synthesis and detoxification of drugs and toxins. The endoplasmic reticulum is a vital organelle in eukaryotic cells and is essential for many cellular processes.

what meaning of Hyperthyroidism: Fx of Anti-thyroid medications'
Answers
Hyperthyroidism is a medical condition characterized by the excessive production of thyroid hormones by the thyroid gland. This overactivity can lead to various symptoms such as weight loss, increased heart rate, anxiety, and intolerance to heat.
Anti-thyroid medications are a group of drugs used to treat hyperthyroidism by reducing the production of thyroid hormones. Two common types of anti-thyroid medications are methimazole and propylthiouracil (PTU). These medications work by inhibiting the enzyme thyroperoxidase, which is essential for the synthesis of thyroid hormones (T3 and T4) from iodine and tyrosine.Here's a step-by-step explanation of how anti-thyroid medications function:1. The patient takes the prescribed anti-thyroid medication, such as methimazole or PTU.
2. The medication enters the bloodstream and is transported to the thyroid gland.
3. Once in the thyroid gland, the medication blocks the action of thyroperoxidase enzyme.
4. The inhibition of thyroperoxidase leads to a decrease in the production of thyroid hormones (T3 and T4).
5. With lower levels of thyroid hormones, the symptoms of hyperthyroidism are alleviated, and the body's metabolic processes return to normal.Anti-thyroid medications are typically prescribed as a long-term treatment for hyperthyroidism. They can effectively manage the symptoms and restore hormone balance. However, it's crucial to monitor thyroid hormone levels regularly during treatment to ensure the proper dosage and avoid potential side effects. In some cases, additional treatments such as radioactive iodine therapy or surgery may be necessary if medication alone is insufficient.

Sickle Cell Anemia/Mutations in hemogoblin gene
Answers
Sickle cell anemia is an inherited blood disorder caused by mutations in the hemoglobin gene, specifically the beta-globin subunit.
The abnormal hemoglobin molecules result in the formation of sickle-shaped red blood cells, which can get stuck in small blood vessels, leading to tissue damage, pain, and other complications.
There are several types of mutations that can occur in the hemoglobin gene, but the most common one that causes sickle cell anemia is a point mutation, where a single nucleotide is changed from adenine to thymine. This changes the amino acid sequence of the beta-globin protein, leading to the production of abnormal hemoglobin molecules.
Sickle cell anemia is more common in people of African descent, but it also occurs in people of Hispanic, Middle Eastern, and Mediterranean descent. Individuals who inherit one copy of the mutated gene from each parent will have sickle cell anemia, while those who inherit only one copy of the mutated gene will have sickle cell trait, which is generally asymptomatic but can lead to complications under certain conditions.
Treatment for sickle cell anemia focuses on managing symptoms and preventing complications. This may include blood transfusions, pain management, and medications to prevent infections and blood clots. In some cases, bone marrow or stem cell transplants may be an option for a cure, but this is a risky and complex procedure with potential complications. Research is ongoing to find new treatments and a cure for sickle cell anemia.

54) Paracrine feedback from the ________ in the distal tubule to the granular cells stimulates release of ________.
Answers
Paracrine feedback from the macula densa cells in the distal tubule to the granular cells stimulates release of renin.
A distinct organ in the kidneys called the juxtaglomerular apparatus aids in controlling fluid balance and blood pressure. Changes in the sodium concentration of the filtrate that moves through the distal tubule can affect the macula densa cells.
These cells release a paracrine signal that prompts the nearby granular cells to release the renin enzyme when sodium levels are low. Angiotensin I is created by the action of renin on the protein angiotensinogen, which is then changed into angiotensin II by the enzyme ACE. A strong vasoconstrictor, angiotensin II can constrict blood vessels and raise blood pressure.

How do even and odd numbered fatty acids differ in terms of processing during β-oxidation?
Answers
In the human body, oxidation of fatty acids takes place in a number of cell areas, including the mitochondria, where only beta-oxidation takes place, the peroxisome, where alpha- and beta-oxidation take place, and the endoplasmic reticulum, where omega-oxidation takes place.
While fasting and in other situations with high energy demands, such as exercise, beta-oxidation contributes significantly to metabolic energy.
These metabolic circumstances cause the release of fatty acids from adipose tissue as a result of the production of circulating mediators that speed up lipolysis, such as adrenaline and glucagon.
When glycogen and gluconeogenic precursors are in short supply, this metabolic pathway significantly contributes to the energy needs of skeletal muscle, cardiac muscle, and kidneys.
