Hormones in plants and in humans

Insulin [blank_start]reduces[blank_end] blood sugar levels by converting [blank_start]glucose[blank_end] into [blank_start]glycogen[blank_end] in the [blank_start]liver[blank_end]

When blood sugar levels decrease [blank_start]glucagon[blank_end] is secreated from the [blank_start]pancreas[blank_end] which breaks down [blank_start]glycogen[blank_end] in the [blank_start]liver[blank_end] to [blank_start]glucose[blank_end]

The nervous system uses [blank_start]electrical impulses[blank_end] to enable you to react to your surroundings and [blank_start]control[blank_end] what you do. Cells called [blank_start]receptors[blank_end] detect changes in the environment known as stimui. Impulses from receptors pass along [blank_start]sensory[blank_end] neurones to the brain. Impulses are sent from the [blank_start]brain[blank_end] to the [blank_start]effector organs[blank_end] along [blank_start]motor[blank_end] neurones.

Nerve impulses pass across a synapse gap by the [blank_start]diffusion[blank_end] of [blank_start]neurotransmitters[blank_end]

A tropism is a plant's response to light

Positive tropism is when the plant moves [blank_start]towards[blank_end] [blank_start]a stimulus[blank_end]

What do auxins do?

Carbohydrates in our food are broken down to [blank_start]glucose[blank_end], which is absorbed into the [blank_start]blood[blank_end]. As the concentration of glucose in the blood rises, the [blank_start]pancreas[blank_end] senses a change and releases a hormone called [blank_start]insulin[blank_end]. This hormone travels to the liver in the blood. The [blank_start]liver[blank_end] starts removing [blank_start]glucose[blank_end] from the blood and turning it into [blank_start]glycogen[blank_end]. This is stored in the [blank_start]liver[blank_end], when blood glucose levels get very low, the [blank_start]pancreas[blank_end] senses the change and produces another hormone called [blank_start]glucagon[blank_end]. This hormone also travels to the liver, where [blank_start]glycogen[blank_end] is turned back into [blank_start]glucose[blank_end] and released back into the blood. (This is an example of [blank_start]negative[blank_end] [blank_start]feedback[blank_end])
