vitamin
glucose
citric acid

cellular respiration is a biochemical process that converts nutrients into ___.
the main energy - carrier molecule in cells is ___.
the first stage of cellular respiration, called glycolysis, occurs in the ___ of the cell.
in glycolysis, one molecule of ___ is broken down into two molecules of pyruvate.
the second stage of cellular respiration is the citric ___ cycle, which happens in the mitochondria.
during the citric acid cycle, pyruvate is converted into carbon ___, which is released as waste.
the last stage of cellular respiration, the ___ transport chain, produces the most atp.
___ is the final electron - acceptor in the electron transport chain.

Explanation:

Cellular respiration converts nutrients to energy. ATP is the main energy - carrier. Glycolysis occurs in the cytoplasm and breaks down glucose. The second stage is the citric acid cycle in mitochondria, where pyruvate is converted to carbon dioxide. The electron - transport chain is the last stage and oxygen is the final electron acceptor.

Answer:

1. energy
2. ATP
3. cytoplasm
4. glucose
5. citric acid
6. dioxide
7. electron
8. Oxygen
