Front

What is the full name for the bacteria shape/conformation known as 'Streptococcus'?

Back

Streptococcus is a genus of spherical bacteria that often form chains.

Front

What organelle releases energy for cells to use, particularly in animal muscle cells?

Back

Mitochondria are the organelles responsible for energy production in cells.

Front

How do enzymes affect the speed of a reaction and the amount of energy required?

Back

Enzymes make a reaction go faster and use less energy.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides a stiff, protective outer layer for plant cells.

Front

What organelle directs all cell activities through the DNA located there?

Back

The nucleus directs all cell activities and contains the cell's DNA.

Front

What is the primary function of mitochondria in cells?

Back

The primary function of mitochondria is to produce ATP, the energy currency of the cell.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up biological reactions without being consumed.

Front

What is the structure that surrounds and protects plant cells?

Back

The cell wall is the structure that surrounds and protects plant cells.

Front

What is the significance of the nucleus in eukaryotic cells?

Back

The nucleus is significant because it houses the cell's genetic material and controls cellular activities.

Front

What type of bacteria is characterized by a spherical shape and often forms chains?

Back
