3. How do plants, such as trees, play a role in the carbon cycle?
ArbitrLikvidat [17]

Answer:

Plants go through a process called photosynthesis that allows them to take carbon dioxide out of the air and turn it into oxygen and energy. The oxygen will later be breathed in by an animal and go through cellular respiration where it will become CO2 again.

Which of the following is a normal process of photosynthesis that could not occur if all reaction centers were inactivated by a
Arturiano [62]

Answer:

A. donation of excited electrons by chlorophyll a to a primary electron acceptor

Explanation:

Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.
