During the aerobic pathway of carbohydrate metabolism, _______.
Phantasy [73]
The answer would be: <span>ATP </span><span>is formed slowly, but muscular activity can be sustained for many hours

The main substrate used in aerobic pathway would be glucose, not fatty acids. The glucose will be oxidized by oxygen, not carbon dioxide. The reaction is slow but it will produce much more ATP than the anaerobic pathway. More ATP means there is more energy produced so aerobic pathway is more efficient.

Why are the lysosomes useful during entrapment of particles?
Elena L [17]

Answer:

Lysosomes

Explanation:

Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.
