They protect the skin from attacks by predators, parasites and other injuries.
Carbohydrates are an important type of FOOD MACRO MOLECULES.
Food macro molecules refers to the small chemical sub units of molecules which are found in food. There are four major food macro molecules, they are carbohydrates, proteins. lipids and nucleic acids.
Carbohydrate is an important source of fuel for the biological system.
The sugar and phosphate portion of the nucleotides are found as segments of the rails on the DNA twisted ladder.
That cell is called ribosome.
Answer:
Both electron transport and a proton gradient
Explanation:
The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.
Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.
Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.
Thus, the selected option is correct.
