Front

What is the function of the cell membrane?

Back

The cell membrane is selectively permeable, regulating which materials enter and leave the cell.

Front

What is the process represented by the equation 6CO2 + 6H2O + light energy → C6H12O6 + 6O2?

Back

This process is called Photosynthesis.

Front

What are the muscular contractions of the esophagus that help push food down called?

Back

These contractions are called Peristalsis.

Front

What is a taproot?

Back

A taproot is a large, central root that grows deeper than other roots, as seen in plants like carrots.

Back

Enzymes are specific, meaning each type of enzyme catalyzes a specific reaction.

Front

Define selectively permeable.

Back

Selectively permeable means that a membrane allows certain substances to pass while blocking others.

Front

What is the role of photosynthesis in plants?

Back

Photosynthesis allows plants to convert light energy into chemical energy in the form of glucose.

Front

What is peristalsis and where does it occur?

Back

Peristalsis is the wave-like muscle contractions that move food through the digestive tract, particularly in the esophagus.

Front

What distinguishes a taproot from a fibrous root?

Back

A taproot is a single, thick root that grows deep, while fibrous roots are thin and spread out.

Front

Why does the body need different types of enzymes?

Back

The body needs different types of enzymes because each enzyme is specific to a particular substrate and reaction.
