Which organelle is responsible for producing ATP through cellular respiration?
Answer: Mitochondria
Mitochondria generate most of the cell's ATP via oxidative phosphorylation in their inner membrane.
In which phase of the cell cycle does DNA replication occur?
Answer: S phase
DNA replication occurs during the S (synthesis) phase of interphase, before the cell enters mitosis.
Which blood cell type is responsible for the adaptive immune response?
Answer: Lymphocytes
Lymphocytes (B cells and T cells) mediate the adaptive immune response through antibody production and cell-mediated immunity.
What type of joint allows for the widest range of motion in the human body?
Answer: Ball-and-socket joint
Ball-and-socket joints, such as the hip and shoulder, permit movement in all planes, giving the greatest range of motion.
Which division of the autonomic nervous system prepares the body for 'fight or flight'?
Answer: Sympathetic division
The sympathetic division increases heart rate, dilates pupils, and directs blood to muscles in response to stress.
What is the correct order of blood flow through the heart?
Answer: Right atrium → right ventricle → lungs → left atrium → left ventricle → body
Deoxygenated blood enters the right atrium, moves to the right ventricle, travels to the lungs, returns to the left atrium, then left ventricle before being pumped to the body.
The knee joint is classified primarily as what type of joint?
Answer: Hinge joint
The knee is primarily a hinge joint that allows flexion and extension, though it has minor rotational capability.
