Which of the following is NOT a component of the endomembrane system? Endoplasmic reticulum (ER), Golgi complex, Ribosomes, Lysosomes, Plasma membrane

Back

Ribosomes

Front

What is the role of the endoplasmic reticulum in cells?

Back

The endoplasmic reticulum provides mechanical support by helping cells maintain shape and plays a role in intracellular transport.

Front

Which of the following is associated with membrane-bound ribosomes, allows for the compartmentalization of cells, and helps carry out protein synthesis? Options: Rough ER, Smooth ER, Golgi complex, Lysosome

Back

Rough ER

Front

Smooth ER functions include the _______ of cells and lipid synthesis.

Back

detoxification

Front

What is the main function of the Golgi complex in cells?

Back

It correctly folds and chemically modifies newly synthesized cellular products and packages proteins for trafficking.

Front

Mitochondria have a double membrane that provides compartments for different metabolic reactions involved in _______.

Back

aerobic cellular respiration

Front

Lysosomes are membrane-enclosed sacs that contain _______ enzymes that digest material and play a role in programmed cell death (apoptosis).

Back

hydrolytic

Front

What is the role of vacuoles in plant cells?

Back

Vacuoles in plant cells maintain turgor pressure through nutrient and water storage.

Front

Effect of surface area-to-volume ratios on material exchange between cells or organisms and the environment.

Back

A higher surface area-to-volume ratio increases the efficiency of material exchange.
