What do mitochondrial and thylakoid membranes ave in common?
Mitochondrial and thylakoid membranes are sites of electron transport chains. They both use ATP synthase proteins in ATP production.
What is the purpose of the inner mitochondrial membranes being five times the area of the outer mitochondrial membranes and 17 times that of the cells plasma membrane?
It increases the surface for oxidative phosphorylation
What are mitochondria surrounded by?
Mitochondria are surrounded by membranes.They have two membranes.
The difference in charge on the inside and the outside of mitochondrial membranes supplies the energy to what?
The formation of ATP.
What is the space inside the folds of the inner mitochondrial membranes?
The space on the very inside of the mitochondria past the cristae (folds in the inner membrane) is called the mitochondrial matrix.
What determines whether or not a substance can actively transported through the membranes?
Active transport can only occur at intact, closed membranes. Such membranes can envelop very different compartments, like the whole cell, vesicles, the vacuole, the mitochondrial matrix, the inner thylacoid space of the chloroplasts, etc.
Why can steroid and thyroid hormones but not amino acid-based hormones move across cell membranes?
Steroid and thyroid hormones are lipid soluble, allowing them to diffuse directly across cell membranes. Amino acid-based hormones are water soluble and require specific receptor-mediated mechanisms to enter cells.
What do the membranes of micro spheres and those of cells have in common?
they have selectively permeable membranes
How common is thyroid disease?
The thyroid gland is located on the front part of the neck below the thyroid cartilage (Adam's apple). The gland produces thyroid hormones, which regulate body metabolism. Thyroid hormones are important in regulating body energy, the body's use of other hormones and vitamins, and the growth and maturation of body tissues. Diseases of the thyroid gland can result in either production of too much thyroid hormone, thyroid nodules, and/or goiter. All types of thyroid problems in women are much more common than thyroid problems in men.
Common diseases that affect the thyroid gland?
Goiter
Is iodine found in thyroid hormones?
No. Iodine is not found in the thyroid hormones, but Iodine is necessary for the thyroid gland to make thyroxin hormone. Actually yes, iodine is found in the thyroid hormones T3 and T4, the most common forms of thyroid hormone.
What medicines are for hypo thyroid?
Hypothyroidism is usually treated by taking daily thyroid medication. The most common thyroid medication is called levothyroxine. This thyroid medication comes in 12 different strengths and it is prescribed by a physician.
