Front

What is the role of enzymes in chemical reactions?

Back

Enzymes decrease the activation energy of the reaction, allowing it to proceed faster.

Front

What is the purpose of cell cycle checkpoints?

Back

To repair damaged cells before they enter cell division.

Front

What is cytokinesis?

Back

Cytokinesis is the division of the cytoplasm during cell division.

Front

At which checkpoint does the cell check for proper DNA replication?

Back

G2 Checkpoint.

Front

What does the endosymbiotic theory propose?

Back

Eukaryotes evolved from prokaryotic cells.

Front

Which organelles are involved in the endosymbiotic theory?

Back

Chloroplasts and mitochondria.

Front

What is a characteristic of chloroplasts and mitochondria that supports the endosymbiotic theory?

Back

They have circular DNA similar to prokaryotes.

Front

What is the significance of the double membrane in organelles?

Back

It is similar to the structure of prokaryotic cells, supporting the endosymbiotic theory.

Front

What happens at the G1 checkpoint?

Back

The cell checks for DNA damage and ensures it is ready for DNA synthesis.

Front

What is the M (spindle) checkpoint responsible for?

Back

It ensures that all chromosomes are properly attached to the spindle before cell division.
