Front

What is the pH level of black coffee?

Back

Black coffee is acidic.

Front

What is the difference between rough and smooth endoplasmic reticulum (ER)?

Back

Rough ER has ribosomes, while smooth ER does not.

Front

What do molecules require to cross a cell membrane by facilitated diffusion?

Back

They require the aid of transport proteins.

Front

Which structure in a cell is responsible for protein synthesis?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the function of the Golgi body?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

What are lipids?

Back

Lipids are a group of organic compounds that are insoluble in water, including fats, oils, and phospholipids.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules pass through the cell membrane with the help of transport proteins.

Front

What is the primary function of ribosomes?

Back

The primary function of ribosomes is to synthesize proteins.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.
