What type of connective tissue of the newborn children consists of adipocytes that contain numerous fat cytoplasmic?

There is a histologic specimen of loose irregular fibrous connective tissue stained with the dye specific for acid phosphatase (enzyme of lysosomes). Some of the cells in that histologic specimen are characterized by high activity of the enzyme. What cells are those, and what function do they perform.

3. Structural diagram of loose irregular fibrous connective tissue.

Cells and fibres of loose irregular fibrous connective tissue are characterized by structural features. It is necessary to examine the diagram and describe the structural features of the cells and fibres. What function do they perform?

The amino acid asparagine is synthesized from aspartic acid by the enzyme asparagine synthetase (AS).

Propose a scheme where a cell can regulate the expression of AS. Include a figure clearly diagramming the regulation mechanism.

Your scheme should account for the concentrations of asparagine and aspartic acid.

A particular enzyme at a research facility is being studied by a group of graduate students. This enzyme has a Km value of 5.0 X 10-6 M. The students study this enzyme with an initial substrate concentration of 0.055 M. At one minute, 7 μM of product was made. What is the amount of product produced after 5 minutes?What is the Vmax?(Hint: unit of velocity is μM/min)
