Term
photosynthesis
Definition
metabolic pathway where organisms capture light energy and use it to build sugars from water and carbon dioxide
Term
occurs in the chloroplasts
Definition
photosynthesis
Term
Photosynthesizers get energy from
Definition
the sun
Term
animals get energy second- or third-hand from
Definition
plants or other organisms
Term
the energy is converted to the
Definition
chemical bond energy of ATP
Term
plants make ATP during
Definition
photosynthesis
Term
cells of all organisms make ATP by
Definition
breaking down carbohydrates, fats, and protein
Term
anaerobic pathways
Definition
evolved first, don't require oxygen, start with glycolysis in cytoplasm, completed in cytoplasm
Term
aerobic pathways
Definition
evolved later, require oxygen, start with glycolysis in cytoplasm, completed in mitochondria
Term
glucose
Definition
a simple sugar
Term
atoms held together by covalent bonds
Definition
glucose
Term
electron transfer phosphorylation
Definition
occurs in the mitochondria
Term
coenzymes deliver electrons to electron transfer chains

electron transfer phosphorylation
Term
electron transfer sets up
