Among these options, the one which is the broadest group used to classify organisms is D. class.
Although it is not the broadest group ever phylum and kingdom are above it), it is the broadest one here.
Answer:
The correct answer will be- to synthesise the ATP molecules in respiration process.
Explanation:
The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.
The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.
The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.
Thus, to synthesise the ATP molecules in the respiration process.
Answer: Option B.
Neural crest and peripheral nervous system.
Explanation:
Neural crest are bilateral paired cells of the neural tube that arise from the ectoderm layer of the embryo. Thesescells move to different part of the body and differentiate into various cell types like melanocytes,cartilage and bone, smooth muscle, craniofacial, neurons, gangalia e.t.c. The neural crest running through neural tube develop into peripheral nervous system after birth. Peripheral nervous system consist of neurons and gangalia outside the nervous system The peripheral nervous system connect the central nervous system to organs, skin and limbs.
