Answer:
The correct answer is: E) both B and C.
Explanation:
- Bacteria and Archaea forms two distinct and different Domains in the Taxonomic classification system.
- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.
Answer:
c) Acetyl COA carboxylase; citrate
Explanation:
Citrate serves as an allosteric activator for fatty acid synthesis and diverts the cellular metabolism from the consumption of metabolic fuel to the storage of fuel as fatty acids. When the concentrations of mitochondrial acetyl-CoA and ATP increase, citrate is transported out of mitochondria into the cytosol. In the cytosol, citrate serves as the precursor of cytosolic acetyl-CoA and an allosteric activator of acetyl-CoA carboxylase.
The enzyme Acetyl-CoA carboxylase has three functional regions. Its biotin carboxylase activates CO2 and its transcarboxylase transfers activated CO2 from biotin to acetyl-CoA to produce malonyl-CoA.
Yesssssssssssssssssssssirrrrr
Answer: <em>Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:</em>
<em>
</em>
<em>1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
</em>
<em>2. Metaphase: Chromosomes line up at the centre of the cell.
</em>
<em>3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
</em>
<em>4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.</em>
