Plant cells are protected from the harmful effects of excessive light energy and reactive oxidative molecules by__________
a. mitochondria
b. chlorophyll
c. carotenoids
d. atp

Answer:

c. carotenoids

Explanation:

Carotenoids are essential to photosynthesis since they regulate the amount of light plants get and protect plants from receiving excess light energy. Carotenoids regulate the pigments for plants as they manage the amount of light stored in these pigments in order to better harvest sunlight.

Plant cells are protected from the harmful effects of excessive light energy and reactive oxidative molecules by c. carotenoids.

Using light energy, an organic compound is made through photosynthesis. Photosynthetic organisms are organisms that produce energy through photosynthesis.

Carotenoid: The basic structure is composed of eight isoprene units and is lipid-soluble. it has an Absorption between 400 and 500 nm, and colors- yellow, red, and orange. Pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils all have distinctive colors thanks to carotenoids.

Carotenoid's role: Transmission of excitation energy Carotenoids protects plant cells from the harmful effects of excessive light energy and reactive oxidative molecules through photoprotection by acting as a quencher and a scavenger.

Because the pacemaker potential occurs during systole, it can also be called systolic potential. (Click to select) 2. The pacemaker potential is the relatively slow, spontaneous depolarization in the SA node. (Click to select) 3.

The human immune system detects the presence of pathogens using pattern recognition receptor molecules that bind to common components of pathogens, such as peptidoglycan polymers in cell walls and the flagellin protein of bacterial flagella, known as pathogen-associated molecular patterns, or PAMPs. These receptors are effective becauseGroup of answer choicesthey detect only human immune molecules.they result in rapid evolution of the host immune system.they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.PAMPs evolve more quickly than other pathogen molecules.
