Endosymbiotic Theory and Life of a protein

Front

What is the endosymbiotic theory?

Back

The endosymbiotic theory proposes that certain organelles, specifically mitochondria and chloroplasts, originated as free-living prokaryotic organisms that were engulfed by a host cell, leading to a symbiotic relationship.

Front

What evidence supports the endosymbiotic theory?

Back

Evidence includes the presence of their own DNA, double membranes, and similarities in size and structure to prokaryotic cells.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles, such as bacteria.

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a complex cell that contains a nucleus and membrane-bound organelles, found in organisms like plants, animals, and fungi.

Front

What is the monomer of a protein?

Back

The monomer of a protein is an amino acid.

Front

What are the two main types of cells?

Back

The two main types of cells are prokaryotic and eukaryotic cells.

Front

What organelles are known to have arisen from endosymbiosis?

Back

Chloroplasts and mitochondria are organelles that are believed to have arisen from endosymbiosis.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing ATP through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plants.

Front

What is the size comparison between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are generally smaller than eukaryotic cells.
