Document Summary
Insulin producing cell in pancreas produces insulin which circulate throughout body via the bloodstream to the liver and muscle cells. Response: glucose uptake by liver and muscle cell, negative feedback on the stimulus. **positive feedback loop: something small that stimulates a huge reaction. Food = energy received from the environment. Omnivores = regularly consume animals as well as plants or algae (humans) Pandas are better at extracting nutrients from plants than cows as they have adapted many. Chemical energy that"s converted into atp to power cellular processes. Organic building blocks, such as organic carbon & nitrogen to synthesize organic molecules. Essential nutrients which are required by cells and must be obtained from dietary sources. Amino acids that must be obtained from food (we can synthesize 20 amino acids on our own but the rest we can"t these are essential amino acids)
