NO ONE IS HELPING ME PLEASE IM FINNA CRY PUT IT IN YOUR OWN WORD 1. Where does the body get glucose molecules?

2. Where does the body get amino acids?

3. Where does the body get oxygen?

4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?

1. The body gets glucose (sugar) molecules from the forms of glucose they eat through foods. Ex. Carbs, fats, proteins like pasta, bananas, meat, etc

2. Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body's proteins—muscle and so forth—to obtain the one amino acid that is needed.

3. The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart.

4. If the human body doesn't take in one or all of these molecules we'll simply die or we'll be in severe health issues. We use glucose as a form of energy, if we don't take in any energy we'll die. We need amino acids to help break down food in our body, if we don't we'll be in very severe health issues. And of course we need oxygen to be alive. We need oxygen for respiration and photosynthesis to take place. We also need oxygen to burn the fuel in our body to produce energy.

Explanation: Hope this helps! Have a great day!

me i can you if you would like.

within 30 of the equator hope this
