Which accurately describes the function of the electron transport system (ETS)?
SVEN [57.7K]
You are familiar with the electron transport system in photosynthesis that takes light energy and converts it to chemical bond energy in the form of ATP and NADPH. This electron transport chain in cellular respiration will take the energy stored in NADH and FADH2 during the Krebs cycle and convert it to chemical bond energy in the form of ATP. In eukaryotes, this reaction takes place on the inner mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that undergo aerobic respiration also have an electron transport chain located within their plasma membrane, which may be highly folded similar to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps

Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
