Hormones and signal pathways Complete the following paragraph to describe signal transduction as it occurs within plants. Choices may be used more than once or not at all. Chemical signals called play an important role in a plant's ability to respond to a stimulus. These signals bind to receptors, the first step in a cellular response called a may be located in the plasma membrane, the cytoplasm, the nucleus, or the endoplasmic reticulum The series of relay proteins or enzymes activated by the hormone binding the receptor make up the Some responses are immediate, while others require a like Ca", to initiate a cellular response. The result of the transduction pathway is a which is often the transcription of specific genes, resulting in some measurable change. hormones reflex arc signal transduction pathway Signal transducers second messenger response Receptor proteins first messenger

Title: The effect of ethylene production on the unripe banana when are stored together with pear in a bag. Hypothesis: Ethylene is a plant hormone released as a gaseous state into the air by rapidly growing tissues and it affects the surrounding fruits. Iodine solutions bind to the starch of the plant by forming a dark complex. So the darker the fruit, the lesser the content of starch which means the fruit is unripe and vice versa. The lighter color of fruit represents a more ripening status of fruit. Variables. Independent variable: Concentration of ethylene. Dependent variable: Conversion of starch into sugar (ripening of fruit). QUESTION: DESCRIBE 2 CONTROL VARIABLES IN THIS EXPERIMENT: WHAT IS THE METHOD?

During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzyme catalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
