What are the products of light-dependent reactions? Why are they important in light-independent reactions?
tamaranim1 [39]

The products of light-dependent reaction are ATP and NADPH. They are essentially required to fix carbon dioxide and make glucose in light-independent reactions.

Light-dependent reactions are those that use the direct sunlight energy to make usable forms of chemical energy i.e., ATP and NADPH. For this, a pigment called chlorophyll is essential that has the ability to the capture the sunlight.

Light-independent reactions are those that do not directly depend on the sunlight energy to complete their process. Instead they are dependent on the products of light reactions so that they can fix atmospheric carbon dioxide and make glucose for the plant. Calvin cycle is the main process of light-independent reaction.

What part of the respiratory tract is considered the respiratory zone?
Lorico [155]

Answer:

D. Alveoli

Explanation:

Functionally, the respiratory system is separated into a conducting zone and respiratory zone:

Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.

Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).

The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
