Answer:
The answer of ist question FADH2,NADH 2nd question O2 3rd question NAD+,FAD,H2O,ATP.
Explanation:
Ist answer
During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.
2nd answer
During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.
3rd answer
The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.
Answer:
RNA polymerase moves along the template strand in a 3'-to-5' direction.
Explanation:
RNA polymerase is an enzyme involved in the synthesis of an RNA molecule from a DNA molecule. The process of synthesis of an RNA molecule is known as transcription which takes place in the nucleus of eukaryotes.
The DNA strand which is transcribed into the RNA molecule is known as template DNA and run from the 3'to 5' end.
The RNA polymerase enzyme binds to the promoter region which initiates the reaction. The RNA polymerase enzyme forms the RNA molecule in 5'to 3' direction by adding new nucleotide at 3'end, therefore, it has to move on the template strand with 3' to 5' direction.
Thus, the selected option is correct,
Answer:
In plants, the cell wall is full of small holes called plasmodesmata. If there were no cellular membrane all of the fluid in the cell (cytoplasm) would just leak out. The membrane also acts as a barrier to the outside world, controlling the influx of nutrients, hormones, chemicals and other substances the cell uses.
In animals, if there is no cell wall so the absence of a cellular membrane would make all animals a pile of goop on the ground.
