Biology Flashcard

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological processes.

Front

What sugar does RNA contain?

Back

RNA contains ribose, a five-carbon sugar.

Front

Which process produces the highest number of ATP?

Back

The Electron Transport Chain (ETC) produces the highest number of ATP during cellular respiration.

Front

What is a codon?

Back

A codon is a three-nucleotide sequence in mRNA that codes for a specific amino acid.

Front

What happens if an error is found at cell cycle checkpoints?

Back

If an error is found, apoptosis (programmed cell death) may occur.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are proteins, carbohydrates, lipids, and nucleic acids.

Front

What is the primary function of enzymes?

Back

The primary function of enzymes is to catalyze biochemical reactions, lowering the activation energy required.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is single-stranded.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP.
