animals, fungi, most protozoa, most bacteria

define food

Organic molecules used by organisms to produce ATP (cellular fuel).

photoautotrophs

make their own food using energy from the sun

chemoautotrophs

make their food using energy from chemical reactions

photoheterotrophs

digest food using energy from the sun

chemoheterotrophs

digest food using energy from chemical reactions

humans are considered ____ because ______

humans are considered chemoheterotrophs because we eat chemical compounds, like carbohydrates, proteins, fats

What are the two main objectives for heterotrophs when eating?

1. Avoid getting poisoned. 2. Take in all important molecules the body require

Define Allergy and its severe reaction.

Overreaction by the immune system to a harmless substance that is detected as an invader.

Define Intolerance (w/ example).

Problems digesting a compound within food. Example: lactose intolerance.

What is Gluten and what responses does it trigger?

A compound made from proteins in grain seeds (commonly wheat).

Triggers allergy, intolerance, and autoimmune response (celiac disease).

sources of gluten

Sources include wheat products, drugs, and candies.

what does gluten do to dough?

Gives ‘bounce’ to dough. Kneading and incubating the dough lets gluten organize into long, straight molecules that give the bread more elasticity and strength

Allergy immune and severe response

Immune response:  swelling

Severe: anaphylactic shock (dizziness, cramping, difficulty breathing)
