Biology A Unit 5: Lessons 22-26 | QUESTIONS AND ANSWERS 2023/24 Lesson 22: - Lesson 22: What molecule is used to power cellular processes in cells? - ATP What is the role of ATP in transport across a cell membrane? - ATP is an energy molecule that helps with active transport. What statement is true about the relationship between ADP and ATP? - Another phosphate group can be added to ADP to regenerate ATP. What results at the end of biochemical reactions that involve enzymes? - products What do enzymes react with? - a specific substrate What can be said about phenylketonuria? Select all that apply. - It is caused by a mutation on the PAH gene. It causes excess phenylalanine accumulation. Which components are part of ATP's structure? Select all that apply. - adenine ribose phosphate groups What happens when ATP reacts with water to form ADP and a phosphate group? - Energy is released. Determine if the following statement is true or false. ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it. - True Which category of macromolecule does ATP belong to? - nucleotide Which statements correctly describe enzymes? Select all that apply. - They only react with a specific substrate. They speed up chemical reactions. Which statements describe what happens when enzymes are added to a chemical reaction? Select all that apply. - The activation energy is lowered. The chemical reaction is sped up. Where is amylase produced in the human body? - in the salivary glands and pancreas An enzyme catalyzes a chemical reaction, where A and B are joined to yield C. What statement is correct about this reaction? - A and B are reactants. Study the image. Which labeled part is the active site? - B
