Verified step by step guidance

Understand the concept of allosteric proteins: Allosteric proteins are proteins that can change their conformation and activity in response to the binding of an effector molecule at a site other than the protein's active site.

Evaluate the statement 'They are sensitive to environmental conditions': Allosteric proteins can be influenced by changes in pH, temperature, and other environmental factors, which can affect their conformation and activity.

Evaluate the statement 'They are acted on by inhibitors': Allosteric proteins can be regulated by inhibitors that bind to allosteric sites, altering the protein's activity by stabilizing either the active or inactive conformation.

Evaluate the statement 'They exist in active and inactive conformations': Allosteric proteins can switch between different conformations, typically an active form and an inactive form, depending on the binding of allosteric effectors.

Conclude that all the first three statements are true: Since allosteric proteins are sensitive to environmental conditions, can be acted on by inhibitors, and exist in active and inactive conformations, all the first three listed responses are correct.
