Answer:
Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.
Explanation:
Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
<span>Attached to each sugar ring is a </span>nucleotide base<span>, one of the four bases </span>Adenine<span> (A), </span>Guanine<span> (G), </span>Cytosine<span> (C), and </span>Thymine<span> (T). The first two (A, G) are examples of a </span>purine<span> which contains a six atom ring and five atom ring sharing two atoms. The second two (C, T) are examples of a </span>pyrimidine<span> which is composed of a single six atom ring. A </span>base pair<span> is one of the pairs A-T or C-G. Notice that each base pair consists of a purine and a pyrimidine. The nucleotides in a base pair are </span>complementary<span> which means their shape allows them to bond together with </span>hydrogen bonds<span>. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. Hydrogen bonds are not chemical bonds. They can be easily disrupted. This permits the DNA strands to separate for </span>transcription<span> (copying DNA to RNA) and </span>replication<span> (copying DNA to DNA). In our simple model, the entire base pair structure is represented by the single blue rod. Various more elaborate models can be constructed to represent base pairs, including the one above which shows individual atoms and bonds.</span>
Q6: A
Q7:D
Q8:C
Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.
Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.
Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.
Sodium bicarbonate is the long name for baking soda, what it does is it helps stabilize your blood pH.
Hope this helps!
