Answer:
Thyrocalcitonin or TCT
Explanation:
Thyrocalcitonin or TCT is a non-iodinated calcium lowering hormone. It is originating from the parafollicular cells or C cells (C for calcium).
The thyroid gland consists of follicles of cuboidal epithelial cells. These cuboidal cells have a nucleus at the base. These are principal cells responsible for the synthesis of thyroid hormones.
In between these follicular cells, other high cuboidal cells are present, known as parafollicular cells / C cells. These cells synthesise the hormone TCT. When there is high levels of calcium ions in the serum, TCT will release. This lowers the high level of calcium ions in the blood and plasma to normal level. This is done due to the deposition of calcium in the bone.
Answer: Energy is stored in the body primarily as GLYCOGEN in the muscles and liver and as TRIGLYCERIDE in subcutaneous body fat.
Explanation:
We take in food for the purpose of ENERGY, building of worn out tissues of the body and to boost the body immunity. After the intake of food, amino acids from dietary protein are used to synthesize body proteins and other molecules, carbohydrate is used to maintain blood glucose and to build glycogen stores, fat is used for energy or stored in the body.
The body must have a steady supply of energy with some of it coming from the metabolism of glucose.
GLYCOGEN formation occurs when there is excess blood glucose level in the process called glycogenesis. It is the suitable way glucose can be stored as it is insoluble and can not disturb the osmotic pressure of the cells. When food is restricted over time, glycogen stores are expended, and the body must rely on the breakdown of stored GLYCOGEN to be converted to glucose for energy production.
Also, energy for tissues that don't require glucose can come from the breakdown of triglycerides in the adipose tissue. TRIGLYCERIDES are formed by the liver when excess calories are taken, and are stored in the adipose tissues.
<span>Enzymes are biological catalysts (they are proteins). Enzymes regulate metabolic pathways in the body.
e.g. Digestive enzymes in your stomach speed up the hydrolysis and breakdown of carbohydrates, proteins and fats in the food you consume.</span>
The right option is; D) eye color, height, hair color
Inherited traits are characteristics of an organism that are coded in the DNA and are passed on from the parents. Inherited traits occur throughout the life time of an individual and it can also be passed on to the next generation. Examples of inherited traits include; eye color, height, hair color, length of toes and blood type.
I would say that many of our heritable traits are <span>influenced by several genes and by the environnement.
It's, for the biggest part, because of the mutations. You have your heritables traits thanks to your mom and your dad. But a mutation caused by either several rays like ultraviolets or chemicals can changed your traits.
Hope this helps !
