Hello there.

Hey there!
The correct answer is False.
The right lung actually has three lobes while the left lung has two!
Hope this helped and have a great day (:
What structure is found in prokaryotic cells but not eukaryotic cells?
a. a single, circular DNA chromosome found in the cytoplasm
because :
Prokaryotic cells may also contain extrachromosomal DNA, or DNA that is not part of the chromosome. This extrachromosomal DNA is found in plasmids, which are small, circular, double-stranded DNA molecules.
Answer is : C, increase the surface to allow more space for ATP synthesis.
As it produces large amounts of ATP through oxidative metabolism of pyruvates, which are produced by glycolysis.
The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.
Each cell contains a different number of mitochondria The number present is dependent upon how much energy the cell requires. The more energy a cell needs the more mitochondria that will be present. Cells have the ability to produce more mitochondria as needed. They also can combine mitochondria to make larger ones.
The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism.The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle. However, the mitochondrion has many other functions in addition to the production of ATP.
