The energy sotred in food must be converted into a form of energy that the body recognizes: __________

During digestion, complex foods are broken into their simplest forms, carbohydrates into simple ______.

During digestion, complex foods are broken into their simplest forms, proteins into _________.

During digestion, complex foods are broken into their simplest forms, fats into _________.

The stored energy must first converted into ATP by a series of chemical reactions via ___________.

___________ refers to the complex of process by which energy in the forms of ATP is released from the food molecules.

Cellular respiration involves a series of processes and forms ATP with or without the presence of oxygen.

We get energy from food via __________, which uses oxygen to produce ATP.

Aerobic respiration involves three stages: glycolysis, Krebs Cycle, and electron transport.

__________ is a process by which one glucose molecule is broken down into two pyruvic acid/pyruvate to generate two net ATPs in the process.

__________ takes place in the cytoplasm of the cell and involves a series of chemical reactions catalyzed by different enzymes.

Step 1 (Glycolysis): Phosphate groups from two ATP molecules are transferred to the glucose molecule.

Step 2 (Krebs Cycle): The resulting six-carbon compound is broken down into three-carbon compounds containing phosphate groups.

Step 3 (Electron transport): Two NADH molecules are produced and a phosphate group is transferred to each three-caron compound.

Step 4 (Glycolysis): The three-carbon compounds are converted into three-carbon pyruvate producing four ATP molecules.

The ________, the second stage in cellular respiration, continues where glycolysis where left off.
