Answer:
Mg is able to give off two of its electrons to other molecule, not four. ATP, in this case is the aceptor of those electrons
Two correct answers are:
1) Hexokinase cannot bind active ATP when it is not complexed with Mg2+
2) Mg2+ makes the terminal phosphorus atom of ATP more accessible to nucleophilic attack by a glucose-OH group
Explanation:
As Mg occurs naturally as ion Mg++, it is able to give off only two of its electrons to other molecule, then it is possible for ATP to receive two electrons of Mg, forming MgATP2-
The hexokinase reaction, here cited, corresponds to the glucose phosphorylation of its sixth carbon to produce glucose-6-P, which is a glycolysis intermediate. In this way glucose is activated (ATP is initially invested to energize glucose). Later on, Glyceraldehide-3-P is produced, and finally converted to pyruvate, NADH2 and ATP
Answer: A
Explanation: Stainless steel
The 5 stages of mitosis go in this order: Interphase, Prophase, Metaphase, Anaphase, and then finally Telophase. Interphase is the beginning of the process which is yellow. Prophase would be red. Metaphase would be blue. Anaphase isn't shown in one of the ones that is pointed out. Finally Telophase is green. Then starts the process over again with Interphase :)
Homologous structures are features that are similar in structure but appear in different organisms and have different functions, and are also evidence of common Therefor, the striped coat of the zebra and the tiger are homologous features, so D. is the correct answer.
