Cell Component Structure & Function (AP)

Which kind of cell is prokaryotic, may or may not have a cell wall, and has no membrane bound organelles?

• Animal

• Bacteria

• Fungi

• Plant

Cell component found in all cells that manufactures proteins.

Which organelle uses digestive enzymes to break down old cellular components and/or invading bacteria/virsus and recycles those components to other organelles for use in building new macromolecules?

• Gap junction

• Nucleus

• Golgi Body

• Lysosome

Prokaryotic and eukaryotic cells generally have which of the following features in common?

• a nucleus

• cell wall made of peptidoglycan

• ribosomes

• flagella or cilia that contain microtubules

• linear chromosomes

Where do the light dependent reactions of photosynthesis occur?

• in the thylakoid membrane

• inner membrane of chloroplast

• inner membrane of mitochondria

• within the stroma

If you increased folding of the the thylakoid membrane, what would be the likely result?

• decrease rate of reactions

• increase rate of reactions

• have less chlorophyll pigment

• create less ATP

Choose all correct answers. ATP synthesis occurs ___.

• in ribosomes

• in mitochondria.

• in chloroplasts.

• in nucleus.

• in rough ER.

Which of the following processes is most likely to occur as a result of an animal cell receiving a signal to initiate apoptosis?

• Ribosomes will translate mRNA to produce proteins.

• Vesicles will release extracellular growth factors via exocytosis.

• Lysosomes will release digestive enzymes into the cytosol.

• Vacuoles will fuse with the cellular membrane.

Cystic fibrosis is a genetic condition that is associated with defects in the CFTR protein. The CFTR protein is a gated ion channel that requires ATP binding in order to allow chloride ions (Cl−) to diffuse across the membrane.

Identify the most likely cellular location of the ribosomes that synthesize CFTR protein.

• cytoplasmic ribosomes

• rough endoplasmic reticulum

• smooth endoplasmic reticulum

• Golgi apparatus

• nucleus

Where is the site of glucose synthesis in a plant cell?

• mitochondria

• chloroplasts

• endoplasmic reticulum

• lysosome

• ribosome
