It's no longer the dead-end of the carbon cycle. Since the industrial revolution, this material has been taken out of the ground (by Oil and Gas companies) which is for the most part subsequently burned - of which the final by-product is CO2. This fossil material also goes into making plastics and other chemicals - so the "dead-end of the carbon cycle" is not quite so straight forward anymore.
Answer:
A. outside plasma membrane:
1. cell wall 6. flagella
B. outside of the cell
4. fimbriae 5. pilus
C. in cytoplasm
2. nucleoid 3. ribosome
Explanation:
Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.
The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.
Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.
Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
