Front

What is the role of kidneys and lungs in mammals?

Back

The kidneys and lungs play the most important role in regulating blood pH in mammals, maintaining it close to 7.4.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that allows certain molecules to cross membranes with the help of transport proteins, occurring down a concentration gradient without the use of energy.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.

Front

What is the primary energy storage molecule produced during cellular respiration?

Back

ATP (adenosine triphosphate) is the primary energy storage molecule produced during cellular respiration.

Front

What are the six kingdoms of life?

Back

The six kingdoms are Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.

Front

What characterizes organisms in Kingdom Animalia?

Back

Organisms in Kingdom Animalia are multicellular and heterotrophic, meaning they cannot produce their own food and must consume other organisms.

Front

What is homeostasis?

Back

Homeostasis is the process by which cells and organisms maintain a stable internal environment despite changes in external conditions.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically occurring down a concentration gradient.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy, often in the form of ATP.

Front

What is the function of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular processes, including muscle contraction and biochemical reactions.
