Questions and Correct Answers
Double membrane-bound organelle that contains genetic information encoded on
chromosomes ✅Nucleus, Chloroplast(genomes from photosynthesis),
Mitochondria(genomes from ATP/Protein)
Provides structural support and protection for plant cells ✅Cell Wall
A complex of RNA and protein that is the site of proteins synthesis(translation)
✅Membrane Associated Ribosome
Free Ribosome
Network of membranes containing enzymes responsible for synthesizing lipids and
breaking down toxins. ✅Smooth Endoplasmic Reticulum
A common second messenger in cell-cell signaling ✅Cyclic AMP (cAMP) messenger
after the hormone which is insoluble and unable to get through the membrane.
Organelle that contains membranes called cristae, it is responsible for producing
most of the cell's ATP ✅Mitochondria
9+2 structure of microtubules in cilia and flagella ✅Axoneme (made of microtubules
and moves through dynein)
Proteins are targeted to specific locations in the endomembrane system using these as
addresses ✅Vesicles, Signal Sequencing, Carbohydrate tag to fit specific receptor
Digests food items or autodigests damaged organelles through acid hydrolysis.
✅Lysosomes
Stacks of flattened membranes called cisternae, in which proteins are modified (for
example, glycosylated) after they are synthesized. ✅Golgi Apparatus (glycosylated:
adding carbohydrate groups)
This occurs during transduction in cell-cell signaling and amplifies the strength of the
metabolic response to the cell's reception of a hormone. ✅Phosphorylation Cascade
(Kinase sends a phosphate to molecule)
Site of reactions that fix inorganic carbon (CO2) onto organic compounds using the
energy from light. ✅Chloroplast
Structural support for the cell, it is made up of microtubules, microfilaments and
