Cell Resp & Photosynthesis

Which are reactants of cellular respiration?

• Glucose

• Oxygen

• Carbon Dioxide

• Heat

Which are products of cellular respiration?

• water

• Oxygen

• Carbon Dioxide

• ATP

What is the first step of cell respiration?

• Glycolysis

• Citric Acid Cycle (Krebs Cycle)

• Oxidative Phosphorylation

• Fermentation

Which of glycolysis are true?

• It occurs in the cytoplasm, not the mitochondria

• It splits glucose into 2 pyruvate

• All of life does it

• It only produces a little ATP and NADH

• It does not require oxygen

At the end of glycolysis, the pyruvate go ...

• into the nucleus

• into the chloroplast

• into the mitochondria

• out of the cell

Once pyruvate gets converted to acetyl CoA, it goes through the Krebs Cycle, which creates...

• a little ATP

• carbon dioxide

• lots of electron carriers

• oxygen

After the Krebs cycle, MOST of the energy originally from the glucose is now stored in

• pyruvate

• heat

• electron carriers

• ATP

The many electron carriers made in the Krebs cycle then moves to the ________________ for oxidative phosphorylation.

• electron transport chain on the inner mitochondrial membrane

• electron transport chain on the outer mitochondrial membrane

• chloroplast

• electron transport chain on the strip of bacon

The electron carriers deliver their electrons to the electron transport chain, which powers...

• glycolysis

• more electron carriers to be created

• the light reactions

• H+ into the space between the mitochondrial membranes, creating a high [H+]

The hydrogen ions flow down their concentration gradient through ______________, powering it to make a lot of ATP

• NADH

• Ribosomes

• ATP synthase

• NADH synthase
