Questions: Match the receptor type with the usual type of hormone Nuclear receptors Cytoplasmic receptors Membrane receptors [Choose] [Choose ] usually bind membrane soluble hormones usually bind water soluble hormones [Choose]

To match the receptor types with the usual type of hormone they bind, we need to understand the nature of the hormones and the receptors:

1. Nuclear receptors: These receptors are typically located within the cell nucleus and are usually involved in the regulation of gene expression. They generally bind to hormones that can pass through the cell membrane, which are typically lipid-soluble hormones.

2. Cytoplasmic receptors: These receptors are found in the cytoplasm and often bind to hormones that are lipid-soluble. Once the hormone binds, the receptor-hormone complex usually translocates to the nucleus to exert its effects.

3. Membrane receptors: These receptors are located on the cell membrane and typically bind to hormones that are not lipid-soluble, meaning they are water-soluble. These hormones cannot pass through the cell membrane and therefore require a receptor on the surface to initiate a cellular response.

Based on this understanding, the matches are:

• Nuclear receptors: usually bind membrane-soluble hormones.
• Cytoplasmic receptors: usually bind membrane-soluble hormones.
• Membrane receptors: usually bind water-soluble hormones.

In summary, nuclear and cytoplasmic receptors typically bind to membrane-soluble (lipid-soluble) hormones, while membrane receptors usually bind to water-soluble hormones.
