To check knowledge of concepts: What are the similar properties and effects of epinephrine and auxin (plant hormone). Concept introduction: Hormones are signaling molecules produced by animals or plants. Hormones bind only to specific cells based on the corresponding receptors and trigger cellular response. In animals, the secreted hormones reach target cells through the bloodstream, whereas in plants, hormones act locally. Epinephrine and auxin are hormones produced from animals and plants, respectively. They are signaling molecules and they stimulate particular cellular responses in their corresponding organisms.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

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
