Why do some big molecules such as starch, protein and fat need to be digested?

Biology
1 answer:
Veronika [31]3 years ago
3 0

Answer:

Macromolecules such as starches, proteins, and fats store great amount of energy (ATP) by making comlpex chemical bonding. This energy cannot be extracted unless they are digested (broken) first. Therefore, organisms with the help of enzymes break the big molecules to make them simpler compounds. Thereon, energy is extracted through series of chemcial reactions occuring within the animal body, i.e. glycolysis, electron transport chain, etc.

The hydrostatic pressure in the glomerular capillaries is the chief and force pushing the water and the solutes out of the blood and to across the filtration membrane.

The glomerulus was the filtering unit of the kidney, which s a unique bundle of the capillaries and lined by the delicate fenestrated and endothelia, a complex mesh of the proteins that serve as a glomerular the basement membrane and the specialized visceral epithelial cells that also form the slit diaphragms and in between the interdigitating foot processes

The glomerular capillaries are basically the barrier to the distribution of the large plasma proteins and into urine. the Large proteins such as the albumin and IgM are impeded by the capillaries whereas smaller proteins pass through the filtration barrier into the tubular fluid.

If a species makes up a small portion of the community by weight, yet exerts a disproportionate influence on community diversity
Marrrta [24]

Answer:

The correct answer will be- Keystone species

Explanation:

The structure of a community is largely determined by the number of species present in the community called species richness and the species diversity.

The species which can play an important role in determining the community could be of two types the foundation species and keystone species.

The species which directly influence the diversity of a community irrespective of their number and abundance is known as the keystone species.

In the given question since the question has discussed the species which disproportionately influence the diversity of the community is known as keystone species.

Thus, keystone species is the correct answer.
