Front

What is Active Transport?

Back

Active Transport is the process by which energy is used to move substances across a plasma membrane against their concentration gradient.

Front

Define Homeostasis.

Back

Homeostasis is the process of maintaining stable internal conditions in a cell or organism despite external changes.

Front

What is the function of Golgi bodies?

Back

Golgi bodies package materials for transport out of the cell or to other locations within the cell.

Front

What is the purpose of fermentation?

Back

The purpose of fermentation is to produce ATP in the absence of oxygen.

Front

How much Net ATP is produced from one molecule of glucose during cellular respiration?

Back

36 Net ATP are produced from one molecule of glucose during cellular respiration.

Front

What is Passive Transport?

Back

Passive Transport is the movement of substances across a cell membrane without the use of energy, following the concentration gradient.

Front

Explain Facilitated Diffusion.

Back

Facilitated Diffusion is a type of passive transport that uses transport proteins to help move substances across the plasma membrane.

Front

What is Osmosis?

Back

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

Front

Define Cellular Respiration.

Back

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

Front

What are Organelles?

Back

Organelles are specialized structures within a cell that perform specific functions.
