Question

Match the functions listed on the left to the subcellular organelles responsible for those functions listed on the right.

Question 6 options:

12345678910 sub-cellular organellse actually responsible for the packaging of cellular proteins that must be contained within membrane-bound vesicle. Proteins 'packaged' by these organelles would include hydrolytic digestive enzymes that are used within the cell but must be sequestered away from other parts of the cell so they don't digest the cell itself, or enzymes like catalases and dismutases that are concentrated by packaging, or any proteins to be exported from the cell, such as antibodies, hormones, or neurotransmitter molecules. 12345678910 forms the centrioles responsible for spindle formation during cell division 12345678910 complex networks of cellular proteins that form the cytoskeletal frameworks that determine cell shapes, form intracellular trafficking 'highways' that move organelles around within the cells, or form cilia and flagella that beat on the outer surfaces of cells 12345678910 contain acidic hydrolase enzymes that can break down engulfed particulates or aged and dysfunctional cellular components thus function as cellular 'stomachs' 12345678910 extensive membrane bound organelles in cellsl that function as sites for important lipid synthesis and sometimes, as is the case in skeletal muscle cells, serve as a major sites for calcium storage 12345678910 protect cells from excessive oxidative stress by neutralizing superoxide free radicals and hydrogen peroxide molecules via the specialized enzymes they contain (superoxide dismutase and catalase, respectively) 12345678910 cytoplasmic membrane-bound organelles continuous with the nuclear membranes whose outer membranes are studded with ribosomes; they function to post-translationally modify and fold proteins that need to be packaged into membrane-bound vesicles 12345678910 subcellular organelles that are physically constructed of rRNA and protein and function as 'factories' for protein production, i.e. are the sites where translation occurs 12345678910 organelles to which DNA is confined and where the processes of semi-conservative replication and transcription occur 12345678910 subcellular organelles where the bulk of the cell's energy currency (ATP) is produced; often referred to as the 'powerhouses' of the cell

Answer 1

1. Sub-cellular organelle actually responsible for the packaging of cellular proteins that must be contained within membrane-bound vesicle. Proteins 'packaged' by these organelles would include hydrolytic digestive enzymes that are used within the cell but must be sequestered away from other parts of the cell so they don't digest the cell itself, or enzymes like catalases and dismutases that are concentrated by packaging, or any proteins to be exported from the cell, such as antibodies, hormones, or neurotransmitter molecules. - Golgi apparatus

2. forms the centrioles responsible for spindle formation during cell division – Centrosomes

3. complex networks of cellular proteins that form the cytoskeletal frameworks that determine cell shapes, form intracellular trafficking 'highways' that move organelles around within the cells, or form cilia and flagella that beat on the outer surfaces of cells – Microtubules and microfilaments

4. contain acidic hydrolase enzymes that can break down engulfed particulates or aged and dysfunctional cellular components thus function as cellular 'stomachs' - Lysosomes

5. extensive membrane bound organelles in cellsl that function as sites for important lipid synthesis and sometimes, as is the case in skeletal muscle cells, serve as a major sites for calcium storage – Smooth Endoplasmic reticulum

6. protect cells from excessive oxidative stress by neutralizing superoxide free radicals and hydrogen peroxide molecules via the specialized enzymes they contain (superoxide dismutase and catalase, respectively - Peroxisomes

7. cytoplasmic membrane-bound organelles continuous with the nuclear membranes whose outer membranes are studded with ribosomes; they function to post-translationally modify and fold proteins that need to be packaged into membrane-bound vesicles – Rough endoplasmic reticulum

8. subcellular organelles that are physically constructed of rRNA and protein and function as 'factories' for protein production, i.e. are the sites where translation occurs - Ribosomes

9. organelles to which DNA is confined and where the processes of semi-conservative replication and transcription occur – Nucleus

10. subcellular organelles where the bulk of the cell's energy currency (ATP) is produced; often referred to as the 'powerhouses' of the cell – Mitochondria
