<u><em>-Describe the electron transport chain. What part of the cells does hit reaction take place in?
</em></u>
The electron transport chain is A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis. The electron transport chain occurs in the inner membrane of the mitochondria.
<u><em>-What molecule stores the energy that is generated during cellular respiration?
</em></u>
Cells create energy by breaking down the ATP molecules. Thus, cellular respiration is the utilization of oxygen for the synthesis of ATP. Glucose is broken down to supply energy for cellular respiration.
To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.
Answer:
Transcription & translation (Ans. A)
Explanation:
Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.
In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.
