    1. GLP-1, or glucagon-like peptide 1, is generated by enteroendocrine cells in the small intestine in response to food in the GI system and promotes satiety by interacting with the hypothalamus

      separate these into multiple sentences and explain

    2. gluconeogenesis and glycogenolysis in order to release glucose into the bloodstream and raise blood glucose levels.

      separate into a few sentences, explain each step by step

    3. -THE MORE YOU KNOW- (ACCEPT WITH MINOR EDITS)

      This entire GLUT section needs to be reformatted. more clearly explained. step by step, explain the tissues, the definitions, etc.

    4. Four different transmembrane transporters found on different cells are responsible for this:

      Where are we now? there is no clear introduction to where we are in this process. There is no diagram indicating what topic we are on. The way this chapter is written is quite difficult to follow

    5. measuring the amount of hemoglobin that is glycated, meaning how much of our hemoglobin is bound to glucose.

      What measures the amount of hemoglobin? very vague and unclear here

    6. Insulin is used throughout the body to increase cellular uptake of glucose to fuel cellular functions as well as increasing glycogenesis in the liver and skeletal muscle when Blood Glucose concentrations are high.

      start by saying when blood glucose concentrations are high....

      I agree this needs to be separated into paragraphs to explain the phenomena, the diagram should be here just to aid in the understanding

    7. One type of cell are the ɑ-cells, or Alpha cells, which aid in the secretion of glucagon. When blood sugar is low, glucagon is released by the Alpha cells, which in turn cause the liver to release glucose into the bloodstream. Other cells include 𝜷-cells, or Beta cells, for the secretion of Insulin when glucose levels in the bloodstream are too high. Insulin triggers the production of glucose into glycogen so that the sugar can be stored for later use.

      define glucagon, and more thorough explanation of this process- step by step

    8. During embryonic development, the pancreas is formed from two separate masses (the dorsal and ventral pancreas), which converge to form the full pancreas. The dorsal pancreas develops into the body and tail of the pancreas, while the ventral pancreas develops into the head of the pancreas. All regions are responsible for housing vital cell types that synthesize and secrete various hormones and peptides through a ductal system that runs throughout the body of the pancreas.

      consider having this paragraph first in this section. or taken out completely

    9. Beta cells make insulin. This peptide hormone is released when the concentration of glucose is high.

      This sentence should be formatted better. talk more about the beta cells here, define them as the alpha cells are suggested to define. where did the peptide hormone sentence come from? please set up the sentences first. for example... another islet of Lange .... is ..... this cell is defined as..... is responsible for...

    10. Alpha cells are responsible for synthesizing glucagon, a peptide hormone secreted into the bloodstream when the concentration of glucose is low.

      this sentence needs to be moved around. first define then state what it is responsible for

    11. Amylases are enzymes that break down starches into simple sugars, while peptidases break down peptide chains into amino acids. Nucleases break down nucleotides into nucleic acids and lipases break down fats to fatty acids.

      i think this would be better as a bulleted, definition list

    12. which promotes glucose intake from the bloodstream – and glucagon – which promotes glucose release into the bloodstream. The opposing actions of the two hormones, insulin and glucagon, keeps physiological blood-sugar levels at a homeostatic state

      I think its important to elaborate on this section or take it out all together

    13. The primary function of the pancreas is to regulate the release of insulin

      responsible for keeping homeostatic glucose regulation -- I think it might be interesting to include that there is evidence of influence of the brain stem having activity on the pancreas

    1. Hormones can be classified in a number of different ways. One of those ways is by the proximity of their target cells or tissues, or in other words, by the type of cell signaling (Fig.1). Endocrine hormones travel to their targets through blood plasma over long distances. Paracrine hormones travel short distances to local targets. The target cells of autocrine hormones are the cells that secrete them. Exocrine hormones are unusual, in that they are secreted outside of an organism. One notable example of exocrine hormones are pheromones, which elicit responses from other organisms. These hormones are also called ectohormones.

      signaling types should be in the format of bullet points each signaling types should include more information
