There are two types of alveolar cells. The type I alveolar cells which lines the alveoli and much more abundant than type II alveolar cells. Then the type II alveolar cells lesser in number but functions differently than type I alveolar cells. Type II alveolar cells secrete surfactant (composed of lecitin and sphingomyelin) for the lungs. Surfactant reduces the surface tension inside the alveoli, preventing alveolar consolidation. This is important as babies with dysfunctional type II alveolar cells (usually preterm babies less than 32 weeks age of gestation) will have respiratory distress syndrome in the absence of surfactant.
Answer:
A) Adenosine triphosphate, or ATP, is an organic compound that provides energy for many different metabolic processes. In the chloroplasts, ATP is a product of the first stage of photosynthesis, and it provides energy for the second stage. NADPH is an energy-carrying molecule created during the first part of photosynthesis when chloroplasts convert light energy into chemical energy. NADPH provides the energy needed for plants make sugar from carbon dioxide in the second stage of photosynthesis.
B) In photosynthesis in presence of sunlight plant utilizes carbon dioxide and water to produce carbohydrates and oxygen.
And the Oxygen is released out by the plant during day time. The released Oxygen is utilized by the living organism and undergo the process of respiration.
C) There is no one “most important” enzyme, but Rubisco is the catalyst that plants use to fix atmospheric carbon into biomolecules as part of photosynthesis. It is hyperabundant, representing a significant proportion of soluble protein in leaves, and is thought to be the most abundant protein on Earth.
