What type of cellular transport is characterized by the expulsion of materials from a cell?

Back

Exocytosis

Front

What is the process called where glucose is broken down into two pyruvate molecules, producing two ATP and two NADH?

Back

Glycolysis

Front

What are the positively charged particles found in the nucleus of an atom?

Back

Protons

Front

What type of bond is formed when two atoms share valence electrons?

Back

Covalent Bond

Front

What is the term for the movement of water across a semipermeable membrane?

Back

Osmosis

Front

What is the primary function of the electron transport chain in cellular respiration?

Back

To produce ATP through oxidative phosphorylation.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain.

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.

Front

What is the main purpose of fermentation in cells?

Back

To regenerate NAD+ for glycolysis in the absence of oxygen.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.
