densk [106]

Answer:

The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.

One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.

Explanation:

The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.

PLEASE HELP ME <br> What are the steps to photosynthesis
RoseWind [281]

Explanation:

During photosynthesis, molecules in leaves capture sunlight and energize electrons, which are then stored in the covalent bonds of carbohydrate molecules. That energy within those covalent bonds will be released when they are broken during cell respiration. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago.

Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. Because they use light to manufacture their own food, they are called photoautotrophs (“self-feeders using light”). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs (“other feeders”) because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight’s energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs.

HELP PLEASE<br> Why do you think genetic diversity is an advantage of sexually reproduction?
Delvig [45]

Answer:

Genetic diversity is an advantage of sexual reproduction because it reduces the occurrence of unfavorable genetic traits and a variety of genes would lessen the chance of the extinction of a population due to environmental changes. The variation between a genetically diverse species will guarantee at least some of it survive when presented with different climates or challenges.
