Front

What type of organic molecules are enzymes?

Back

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

Front

What are the subunits of DNA and their function?

Back

The subunits of DNA are nucleotides, which store genetic information.

Front

What happens before mitosis begins?

Back

Before mitosis begins, the DNA replicates to ensure that each daughter cell receives an identical set of chromosomes.

Front

What is the consequence of removing all mitochondria from a plant cell?

Back

The plant cell will be unable to carry out respiration, which is essential for energy production.

Front

What process is demonstrated when the body sweats to reduce temperature during exercise?

Back

This process is known as homeostasis, which maintains stable internal conditions.

Front

What is the primary function of proteins in the body?

Back

Proteins serve as building blocks for tissues, enzymes, and hormones, playing a crucial role in bodily functions.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

Front

What is photosynthesis and where does it occur?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy, occurring in chloroplasts.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.
