question 22

Multiple Choice

When scientists placed ATP Synthase linked to fluorescent actin on a microscope slide and added ATP,the actin could be seen spinning.If the scientists instead added ADP what would happen?

• A)The actin would not spin because only ATP can move through the channel in ATP synthase.
• B)The actin would spin when ADP is phosphorylated to form ATP.
• C)The actin would not spin because it required ATP hydrolysis.
• D)The actin would spin because ADP can also move through the channel in ATP synthase.
