What is active transport?

Back

Active transport is the process by which substances move across a cell membrane from a low concentration to a high concentration using energy (ATP).

Front

What role do lipids play in cells?

Back

Lipids serve as long-term energy storage and are essential components of cell membranes.

Front

What is the primary function of glucose in living organisms?

Back

Glucose is a simple sugar that serves as a primary energy source for cells.

Front

How does increased carbon dioxide in oceans affect marine life?

Back

Increased carbon dioxide levels can lead to the dissolution of calcium carbonate, weakening marine organisms that rely on it to build their shells.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

Define diffusion.

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

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

Front

What are proteins and their functions?

Back

Proteins are organic molecules that perform a variety of functions including catalyzing biochemical reactions, providing structural support, and facilitating communication between cells.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

What is the significance of calcium carbonate (CaCO3) in marine ecosystems?

Back

Calcium carbonate is crucial for marine organisms like clams and corals, as it is used to build their shells and skeletons.
