Homeostasis and Regulation Concept 2

What is homeostasis?

• Homeostasis is the growth and development of an organism.
• Homeostasis refers to the ability to adapt to external environments.
• Homeostasis is the maintenance of stable internal conditions in an organism.
• Homeostasis is the process of aging in organisms.

What is a receptor?

• A receptor is a carbohydrate that stores energy.
• A receptor is a type of hormone.
• A receptor is a cell that produces antibodies.
• A receptor is a protein that detects and responds to external signals.

A stimulus is?

• A stimulus is a physical object that cannot be perceived.
• A stimulus is a type of medication.
• A stimulus is a form of entertainment.
• A stimulus is an event or object that elicits a response.

An effector is?

• A process that amplifies a biological signal.
• A type of signal that triggers a response.
• A receptor that detects environmental changes.
• A molecule or structure that executes a specific function in response to a signal.

What is the effect caused by a stimulus called?

• Trigger
• Response
• Impulse
• Reaction

Feedback inhibition is?

• A process where the end product enhances its own production.
• A mechanism that promotes the production of all enzymes equally.
• A feedback loop that only occurs in plant cells.
• The output of a process is used as an input to control the behavior of the overall process itself, usually leading to inhibition of the process

Passive transport is?

• A method that requires energy to move substances across cell membranes.
• A process that allows substances to move across cell membranes without added energy.

• A type of active transport that uses ATP to function.
• A process that only occurs in plant cells.

Which transport moves molecules from a high concentration to a low concentration?

• Diffusion
• Osmosis
• Active transport
• Facilitated diffusion

Active transport is?

• the movement of molecules against their concentration gradient, requiring energy.
• the random movement of molecules in a solution, requiring energy.
• the passive diffusion of molecules across a membrane without energy.
• the movement of molecules with their concentration gradient, requiring no energy.

Which type of transport moves molecules from low concentration to high concentration?

• Facilitated diffusion
• Osmosis
• Passive transport
• Active transport
