What is Translation?

Back

Translation is the process by which ribosomes synthesize proteins using messenger RNA (mRNA) as a template.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack membrane-bound organelles and nuclei, while eukaryotic cells contain membrane-bound organelles and have a defined nucleus.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes decrease the activation energy required for a reaction to occur, thus speeding up the reaction.

Front

What is Facilitated Diffusion?

Back

Facilitated Diffusion is the process by which molecules move across the cell membrane from an area of high concentration to an area of low concentration through a channel protein.

Front

What causes lactic acid fermentation in muscles?

Back

Lactic acid fermentation occurs in muscles when cells are struggling to get enough oxygen after intense exercise.

Front

Define Diffusion.

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration without the use of energy.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the difference between active transport and passive transport?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
