Explanation / Answer

2. Collagen scaffolds are ideal for the deposition of cells, such as osteoblasts and fibroblasts and once inserted, growth is able to continue as normal in the tissue.

Hence, the correct answer is option D.

3. Once within cells, glucose is rapidly phosphorylated by glucokinase in the liver and hexokinase in other tissues to form glucose-6-phosphate, which then enters glycolysis or is polymerized into glycogen. Glucose-6-phosphate cannot diffuse back out of cells, which also serves to maintain the concentration gradient for glucose to passively enter cells. So, glucose-6-phosphate is considered as the primary substrate of all neural tissues.

Hence, the correct answer is option B.
