2.7 Ribosomes and Mitochondria Quiz BWHS

The function of the mitochondria is to produce ATP.

• True

• False

Answer explanation

True. Mitochondria are known as the powerhouse of the cell because they produce ATP (adenosine triphosphate), which is the main energy currency in cells.

The mitochondria goes through ___________________ to breakdown __________ to produce _________

• aerobic respiration, glucose, ATP

• anaerobic respiration, glucose, ATP

• aerobic respiration, carbon dioxide, glucose

• anaerobic respiration, carbon dioxide, glucose

Answer explanation

The mitochondria undergo aerobic respiration to break down glucose, which produces ATP. This process requires oxygen and is the primary method for energy production in cells.

Mitochondria are found in which of the following cells

• Bacteria, Plant and Animal Cell

• Bacteria only

• Animal only

• Plant and Animal cells

Answer explanation

Mitochondria are organelles responsible for energy production and are present in eukaryotic cells, specifically in plant and animal cells. Bacteria, being prokaryotic, do not have mitochondria.

The ENERGY processor of the cell is called the ?

• nucleus

• mitochondria

• vacuole

• cytoplasm

Answer explanation

The mitochondria are known as the energy processors of the cell because they produce ATP, the main energy currency. The nucleus, vacuole, and cytoplasm have different functions and do not primarily generate energy.

Who said that "all cells come from other cells?"

• Hooke

• Schlieden

• Schwann

• Virchow

Answer explanation

The statement "all cells come from other cells" is attributed to Rudolf Virchow, who emphasized the importance of cell division in the development of new cells, forming a key principle of cell theory.

Which organelle is the control center of the cell? (It is the BOSS.)

• Nucleus

• Nucleolus

• Golgi Body

• Mitochondria

Answer explanation

The nucleus is known as the control center of the cell because it houses the cell's DNA and regulates gene expression, making it the 'BOSS' of cellular activities.

From which molecules are mRNA molecules transcribed?

• a) tRNA

• b) rRNA

• c) DNA

• d) protein

Answer explanation

mRNA molecules are transcribed from DNA. This process involves copying the genetic information from DNA to produce mRNA, which then serves as a template for protein synthesis. Therefore, the correct answer is c) DNA.

Where are Ribosomes found?

• Inside the Capillaries

• Inside the Cytoplasm of a Cell

• Can't Tell

Answer explanation

Ribosomes are primarily found inside the cytoplasm of a cell, where they play a crucial role in protein synthesis. They can be free-floating or attached to the endoplasmic reticulum, but they are not found inside capillaries.

A ribosome can be best described as...

• a protein factory

• a trash collector

• the powerhouse of the cell

• the brain of the cell

Answer explanation

A ribosome is best described as a protein factory because it synthesizes proteins by translating messenger RNA (mRNA) into amino acid sequences, which are essential for cellular functions.

Which letter is a picture of a ribosome?

• E

• F

• G

• H

Answer explanation

The correct answer is E, as it represents a ribosome, which is a cellular structure responsible for protein synthesis. The other options do not depict a ribosome.
