Answer:

The answer is B. It is an endothermic reaction.

Photosynthesis in an endothermic reaction.

True or False: <br><br> The first step in glycogen synthesis is the phosphorylation of glucose.
r-ruslan [8.4K]

Answer:

The correct answer is True

Explanation:

<u>The first step in glycogen synthesis (glycogenesis) is the phosphorylation of glucose to form glucose-6-phosphate</u>, which is catalyzed by hexokinase. [This step is also the first step in the glycolytic pathway]. Glucose-6-phosphate is then isomerized to glucose-1-phosphate by the action of phosphoglucomutase. This glucose-i-phosphate is then converted to glycogen by glycogen synthase.

Because the human embryo is able to split during early cleavage or blastocyst formation to produce two viable progeny, it is sai
juin [17]

Answer:

This question lacks options, options are:

a) indirect

b) mosaic

c) determinative

d) regulative

e) direct.  

The correct answer is d.

Explanation:

The egg (ovum) like the embryo during the first embryonic divisions, do not possess any sign of polarity. This development mechanism can be called regulative development(in contrast to the mosaic model) since the fate of the cells that originate is not fixed and can be modified during development. In regulative embryos, part of the embryo can be removed and the remaining cells can compensate for the loss and give a complete individual as the final product.The strongest evidence that continues to support this regulatory model is based on the plasticity or potential that mammalian cells possess before implantation. It is known that the blastomeres produced by the first divisions can be replaced with each other or even can be eliminated without apparently altering the embryonic development and therefore they are equivalent (without polarity).
