True/false, if false explain why A protein that binds ATP and transfers a phosphate onto a substrate is called a Protein Phosphatase. - Answer False, a Protein Phosphatase removes phosphates from its substrate; a Protein Kinase transfers phosphates onto its substrate. True/false, if false explain why Indole-3-acetic acid is chemically derived from a nitrogenous base. - Answer False, indole-3-acetic acid, also called auxin, is chemically derived from tryptophan, which is an amino aicd not a ...

Auxin is a plant hormone produced in the shoot tip. Auxin causes cell elongation and travels down the stem from the tip. Auxin is destroyed by sunlight. Explain how this leads to positive phototropism in the plant. Correct Answer Auxin is broken down on the sunny side of the plant. Cells on the shaded side will elongate due to auxin, causing curvature of the stem so that the plant grows towards the light. Ivy plants often use walls or other plants as a support when growing. State the type of ...
