Cell Membrane and Organism Function

Front

What is the primary reason humans cannot digest cellulose?

Back

Humans contain enzymes that can hydrolyze some glycosidic bonds, but they do not recognize glycosidic bonds in cellulose.

Front

What is the energy source for active transport?

Back

ATP hydrolysis.

Front

What drives simple diffusion?

Back

A concentration gradient.

Front

Which microscopy technique is best for viewing internal structures of a mitochondrion?

Back

Transmission electron microscopy.

Front

What happens to bacteria engulfed by white blood cells during phagocytosis?

Back

The vesicle that has engulfed the bacteria will fuse with a lysosome.

Front

Where is the DNA base thymine found?

Back

In the nucleus, mitochondria, and chloroplast.

Front

What are the monomers that make up starch and glycogen?

Back

Glucose.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes digest engulfed materials, such as bacteria.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy (ATP), while passive transport does not.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell.
