What happens during the krebs cycle?
atp and nadh from food are converted to co2 and o2.
nadh from glycolysis is converted to atp and o2 molecules.
glucose is broken down in a cycle of reactions to form pyruvate.
pyruvate is broken down in a series of reactions to form co2.

The correct answer is b.

Explanation:

Hello! Let's solve this!

The Krebs cycle is a process that occurs in the matrix of the mitochondria. It is a metabolic process, cellular respiration.

The reducing agent, the NADH from glycolysis is converted into ATP and O2.

The correct answer is b.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
