Where does the energy for human metabolism come from

Biology
1 answer:
SVETLANKA909090 [29]3 years ago
5 0

Answer:

From food

Explanation:

Food energy is a chemical energy used by humans through the process of cellular respiration. Food contain macromolecules such as lipids, proteins, carbohydrates, water, vitamins, and minerals that are necessary for the human metabolism and they are broken down and used by the series of metabolic steps (glycolysis, Krebs  cycle, electront transport chain and oxidative phosphorilation). Digested macromolecules should be used either as a source of energy or as building blocks for the cell.

At the end of catabolic processes within an organism food energy is transformed into energy usable by the cell-ATP.

C cells of the thyroid gland secrete calcitonin.

<h3>What does C cells of thyroid gland produce?</h3>
  • The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
  • It includes parafollicular cells, or C cells, which release calcitonin.
  • The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
  • When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
  • The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.

Why can't more than one sperm enter an egg?
Y_Kistochka [10]
<span>Only one sperm normally fuses with an egg because if more than one sperm fuses, through a process called polyspermy, development of the zygote usually stops.


</span>
<span>Fertilization of one egg by two sperm is possible, but the resulting zygote is almost never viable because such a zygote would have three sets of chromosomes instead of the normal two. This condition, called triploidy, is usually incompatible with life. Those rare triploid infants that do survive to term have severe and multiple birth defects and rarely live more than a few days. </span>

How can DNA be useful in phylogeny? Question 14 options: A) DNA from every organism in a clade is sequenced to identify genetic
Delvig [45]

Answer:

The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.

Explanation:

The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.

Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.

ahrayia [7]

Answer:

Tolerance

Explanation:

Tolerance is the capacity of an organism to survive changes in certain environmental and biochemical conditions. It has to with changes an organism is able to withstand when is subjected to certain factors which can biotic or abiotic.

For example, in the consumption of alcohol, tolerance can occur when there is a fast elimination of alcohol from the body system. This is usually as a result of the activation of a group of enzymes that is responsible for the metabolism of alcohol in excessive alcohol drinkers. The activation of this enzymes increases the catabolism of alcohol and hence reduces the active time within the body, hence reducing the time by which alcohol intoxicates.
