2nd 9 Weeks DCA Review

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies and packages molecules for transport within or outside the cell.

Front

Which organelle is known as the powerhouse of the cell?

Back

The mitochondria produce energy (ATP) for the cell.

Front

What is endocytosis?

Back

Endocytosis is a type of active transport where cells engulf substances from the outside environment.

Front

What does it mean for an enzyme to be specific?

Back

An enzyme is specific when it only catalyzes a reaction for one particular substrate that fits its active site.

Front

What is facilitated diffusion?

Back

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

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are responsible for producing energy through cellular respiration.

Front

Define active transport.

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the specific reactant that an enzyme acts upon.

Front

What is the difference between diffusion and facilitated diffusion?

Back

Diffusion is the movement of molecules from high to low concentration without assistance, while facilitated diffusion requires transport proteins.
