feedback response, would your heart rate go up or down? If the body initiated a positive-
feedback response, would your heart rate go up or down? - ✔️✔️In a negative-feedback
response, the heart rate would decrease. A positive-feedback response would result in a
heightened heart rate.

List 12 of the organelles discussed in module 1 and briefly state the main function of each. -
✔️✔️plasma membrane, mitochondria, golgi apparatuses, endoplasmic reticulum (smooth and
rough) ribosomes, lysosomes, cilia, cytoplasm, cytosol, chromatin, nucleus, and secretory
vesicles. *We will discuss their individual functions below*
What is the function of the plasma membrane? - ✔️✔️delimits the cell and provides a
boundary between the intracellular and extracellular fluids.
What is the function of the mitochondria? - ✔️✔️synthesizes ATP
What is the function of the golgi apparatuses? - ✔️✔️chemical "packaging plant"
What is the function of the endoplasmic reticulum? - ✔️✔️aids in intracellular transport
What is the function of ribosomes? - ✔️✔️aid in protein synthesis
What is the function of lysosomes? - ✔️✔️break down lipids, polysaccharides, nucleic acids,
etc.
What is the function of cytoplasm? - ✔️✔️lies between the nucleus and the cell membrane
What is the function of cytosol? - ✔️✔️provides essential chemicals and makes up the fluid
part of the cytoplasm
What is the function of chromatin? - ✔️✔️genetic material
What is the function of the nucleus? - ✔️✔️Control center of the cell and holds
deoxyribonucleic acid
What is the function of the secretory vesicles? - ✔️✔️transmitters (i.e. neurotransmitters across
the synaptic cleft)
What is the function of the smooth endoplasmic reticulum? - ✔️✔️aids in intracellular
transport and the production of lipids and carbohydrates
What is the function of the rough endoplasmic reticulum? - ✔️✔️aids in intracellular transport
and in protein synthesis
List the phases of mitosis in order. - ✔️✔️prophase, metaphase, anaphase, and telophase
A protein enters a cell. The outside of the cell has a higher concentration of that protein than
the inside of the cell. Did the protein enter through active transport or passive transport? -
✔️✔️It entered through *active transport* since it is too large to enter through a channel
protein and it is not an ion.
