From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinos
kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

  • Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
  • Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
  • Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
  • Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
  • Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.

True or False. When reactions are too slow to meet the needs of the cell, enzymes are missing from cells and cellular reactions.
EleoNora [17]

Answer:

True

Explanation:

Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular  substrate, for enzyme-substrate complex and later enzyme product complex to formed.

They  act by lowering the activation energy  in the organic chemical reaction therefore increase the rate at which chemical reactions progress.

Hence when  the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.
