What are the two phases of metabolism?
The two phases of metabolism are catabolism and anabolism.
What is metabolism?
Metabolism is the sum of all the chemical processes that occur in the body, including digestion and excretion.
What is catabolism?
Catabolism is the breakdown of complex chemical substances.
What is anabolism?
Anabolism is the building up of complex chemical substances.
What is responsiveness in the context of life processes?
Responsiveness is the body’s ability to detect and respond to changes.
How is metabolism regulated?
Metabolism is regulated by hormones secreted from the endocrine system.
Give an example of responsiveness.
A decrease in body temperature prompts certain white blood cells to move from the blood into affected tissue to help repair it.
Why is responsiveness important?
Responsiveness is crucial for survival, such as when the body reflexively pulls away from a painful stimulus.
What does movement include?
Movement includes motion of the whole body, individual organs, single cells, and tiny structures inside cells.
How does growth occur?
Growth is an increase in body size resulting from an increase in the size of existing cells, an increase in the number of cells, or both.
What is homeostasis?
Homeostasis is the condition of equilibrium in the body’s internal environment due to the constant interaction of regulatory processes.
What are the components of homeostatic control mechanisms?
Homeostatic control mechanisms have three interdependent components: a receptor, integrating center, and effector.
What role does the receptor play in homeostasis?
The receptor senses environmental stimuli and sends information to the integrating center.
What is the function of the integrating center?
The integrating center receives information from the sensors and initiates the response to maintain homeostasis.
What is an example of an effector?
An example of an effector is the kidney, which retains water if blood pressure is too low.
