ANA 111 - The Cell

What is the function of the smooth endoplasmic reticulum

• Protein synthesis

• Synthesis of Lysozomes

• Synthesis of Lipids

• Transport of proteins

With reference to this Image, which of the following is NOT true

• The Nucleolus is visible

• There is abundant smooth endoplasmic reticulum

• Mitochondria are present

• The cell is specialized for protein synthesis

Where are mitochondria primarily located in the cell?

• Nucleus

• Cytoplasm

• Rough endoplasmic reticulum

• Golgi apparatus

Which of the following structures is responsible for the synthesis of Ribosomal RNA (rRNA)?

• Nucleolus

• Nuclear Envelope

• Chhromatin

• Endoplasmic reticulum

Which of the following is true regarding the mitochondrial inner membrane?

• It contains enzymes involved in protein synthesis

• It is highly folded to increase are for ATP production

• It is the site of lipid synthesis

• It is involved in the degradation of cellular waste

Which of the following types of cytoplasmic inclususions is most likely to be found in cells that store large amounts of energy, such as hepatocytes and muscle cells?

• Melanin

• Glycogen

• Lipofuscin

• Crystalline inclusions

With reference to this image, which one of the following statements is true

• The arrows indicate mitochondria

• The structures indicated lack a limiting membrane

• The arrows indicate nucleoli

• The structures indicated are surrounded by a phospholipid bilayer

How does apoptosis differ from necrosis?

• Apoptosis involves cell swelling and inflammation, while necrosis involves controlled cell death and membrane integrity

• Apoptosis leads to cell shrinkage and membrane blebbing without inflammation, while necrosis often resuts in inflammation and cell rupture

• Necrosis involves programmed DNA fragmentation, while apoptosis does not

• Apoptosis only occurs in response to external injurt, while necrosis occurs during normal cellular processes

Which of the following is an example of a static cell population?

• Hepatocyte

• Kidney cell

• Cardiac cell

• Epithelial cell

During which phase of the cell cycle is DNA replicated?

• Prophase

• Anaphase

• G Phase

• S phase
