What is a triacylglycerol ? Discuss the advantages of organisms having triacylglycerol as energy storage molecule?

Biology
1 answer:
Sergeeva-Olga [200]3 years ago
5 0

Answer:

Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.

Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.

Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.

Which statement regarding the energetics of the citric acid cycle is true?(A) All of the energy‑producing capacity of the cycle
Step2247 [10]

Answer:

The correct answer is C production of FAD to FADH2 by the citric acid cycle represent the energetic capacity to synthesize about 1.5 ATP.

Explanation:

Citric acid cycle is one of most important stage of cellular respiration.Citric acid cycle or TCA  cycle composed of various enzyme catalyzed biochemical reaction.

 various reduced coenzymes are produced during TCA cycle such as NADH,FADH2.FADH2 is formed from FAD during the conversion of succinate to fumarate.

  The FADH2 then enter electron transport chain to oxidize itself into FAD along with the generation of 1.5 ATP.

An easy way to calculate the amount of energy available at each level is to
Contact [7]

Answer:

Use the rule that 10% of the energy is transferred between layers.

Explanation:

Energy is transferred between layers of a food pyramid. That means that the  producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).

However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers

SpyIntel [72]

Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.

A farmer wanted to rid his apple trees of a particular leaf-eating insect. he sprayed his trees with an insecticide that killed
marta [7]
The survival of the 2 percent of the population is due to the presence of a gene obtained from other species. This gene must be responsible for developing resistance in the insects, against the insecticide that was used by the farmer. The gene got incorporated in only 2% of the insects and therefore, they survived and rest of them were susceptible to the insecticide and thus, died.
