Which organ is most sensitive to the absence of glucose?
Vikentia [17]

Brain is the organ that is most sensitive to the absence of glucose in the blood. The glucose is needed by the neurons in the brain to carry out their functions. The neurons when deprived of glucose, start to slow down and die out of exhaustion. The lack of glucose can cause symptoms of hypoglycemia, wherein a person starts to experience hallucinations and suffers from excruciating pain in the joints of the bones.

irina [24]

The labeled anatomical features of the muscle filament are attached as an image.

Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.

  • It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
  • Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
  • Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
  • A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.

Thus, the correct labeled anatomical features of the muscle filament is attached as an image.
