A scientist injected some cells with a drug that blocked glycolysis after NADH was formed, but before ATP and pyruvate were formed. All the other enzymes used in cellular metabolism were unaffected. How would the production of ATP in the cell be affected? The cell could not make ATP.
The cell could make ATP using fermentation.
The cell could make ATP using cellular respiration.
The cell could make ATP using the citric acid cycle.

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
