What is the ultimate fate of the electrons that are stripped from glucose during cellular respiration? a) they are donated to nadh. b) they result in the formation of heat. c) they are used to form atp by chemiosmosis. d) they are used to form water.

The correct answer is c) They are used to form ATP by chemiosmosis

Explanation:

In cellular respiration, glucose is oxidized into carbon dioxide and water and  converts into NADH a FADH₂ during glycolysis and Kreb cycle. Then these reduced molecules are used to provide the source of electrons during chemiosmosis.

This transfer of electron to electron transport chain brings the conformation change in proteins that helps in transport of H⁺ions across the inner membrane of mitochondria. This transport of ions increase the proton gradient in the membrane.

So to equalize the proton gradient H⁺ moves towards the matrix through ATPase which allows the formation of ATP from ADP. Therefore the right answer is c) They are used to form ATP by chemiosmosis.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
