Front

What is active transport?

Back

Active transport is the process by which cells move substances across their membrane against their concentration gradient, requiring energy (usually from ATP).

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various cellular functions, including active transport.

Front

What is a Paramecium?

Back

A Paramecium is a unicellular protist characterized by its slipper-like shape and covered in cilia, which it uses for movement and feeding.

Front

What happens to a Paramecium when a chemical is added to its environment?

Back

The Paramecium may stop moving if the chemical affects its cilia or overall cellular function.

Front

What is salivary amylase?

Back

Salivary amylase is an enzyme produced in the saliva that breaks down starches into simpler sugars.

Front

What types of substances can salivary amylase digest?

Back

Salivary amylase primarily digests carbohydrates, specifically starches.

Front

What is the function of enzymes in biological processes?

Back

Enzymes are biological catalysts that speed up chemical reactions in cells without being consumed in the process.

Front

What is the significance of glucose in cellular respiration?

Back

Glucose is a primary energy source for cells, and it is broken down during cellular respiration to produce ATP.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and maintaining homeostasis.
