Energy from sunlight can excite electrons, kicking them out of their orbitals and creating freeradicals. Free radicals are highl
y reactive atoms or molecules that have unpaired electrons and degrade and destroy other compounds in their vicinity. Carotenoids, one of the pigments present in most chloroplasts, can stabilize these free radicals. This suggests that _____. A) once chloroplasts are destroyed, the free radicals will destroy the cell
B) carotenoids probably have a protective function in the cell
C) free radicals induce the synthesis of carotenoids in chloroplasts
D) carotenoids communicate directly with the immune system of plants
Carotenoids are red, yellow or orange shades pigments by numerous plants, parasites, and microscopic organisms.
In plants, carotenoids are found in roots, stems, leaves, blooms, and natural products. Inside a plant cell, carotenoids occur in the films of plastids, organelles encompassed by trademark twofold membranes.
Carotenoids performs the function of protecting chlorophyll from photo-damage by making the free radicals stabilized.
Yes, I think this scheme can work. The chippings will provide enough ethanol to power the mower. The mover requires up to 15% ethanol. As he is distilling it to 95% ethanol, it would be more than enough for the mower to work. And also he can use the remaining ethanol for other purposes like powering Joe’s car or to create alcoholic beverages to drink when Joe’s friends come over to watch UCLA football games on Saturday afternoons.
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
