____ uses light energy from the sun to power chemical process that builds organic molecules.

Plants and other ____ ("self-feeders") are organisms that make their own organic matter-- Including carbohydrates, lipids, proteins, and nucleic acids-- from nutrients that are entirely inorganic

Humans and other animals are ____, "other-feeders", these organisms cannot make organic molecules from inorganic ones.

Most ecosystems depend entirely on photosynthesis for food. For this reason, biologists refer to plants and other autotophs as ____.

Heterotrophs, in contrast to producers, are ____, because they obtain their food by eating plants or by eating animals that have eaten plants.

Cellular respiration is an ____ process, which is just another way of saying it requires oxygen.

The aerobic harvesting of chemical energy from organic food molecules is ____.

Chemical reactions that transfer electrons from one substance to another substance are called oxidation-reduction reactions, or ____ for short.

The loss of electrons during a redox reaction is called ____.

Glucose is oxidized during cellular respiration, losing electrons to oxygen. The acceptance of electrons during a redox reaction is called ____.

The transfer of electrons from organic fuel to NAD+ reduces it to ____.

Electron Transport Chain

In our staircase analogy, the electrons have now taken one baby step down in their trip from glucose to oxygen. The rest of the staircase consists of an ____.

During ____, a molecule of glucose is split into two molecules of a compound called pyruvic acid.

Also called the "Krebs Cycle" completes the breakdown of glucose all the way to CO2, one of the waste products of cellular respiration.

The third stage of cellular respiration is ____.

Your mitochondria have structures that act like turbines. Each of these miniature machines, called an ____, is constructed from protein built into the inner mitochondrial membrane, adjacent to the proteins of the electron transport chains.

This anaerobic "without oxygen" harvest of food energy is called ____.
