Which organelle carries out cell respiration? Each of these organelles has two membranes—a liquid portion and folded, sheet-like membrane structures. What are the names of these four components?

Why can mitochondria be considered the "power plants" of aerobic cells?

A certain eukaryotic cell type specializes in synthesizing lipids. Which organelle would be found in greater abundance in this cell type than in other cell types that don't synthesize lipids? Mitochondria Smooth endoplasmic reticulum Rough endoplasmic reticulum Lysosomes

Match the following:   Mitochondria              Turns light from the sun into energy                                                                                           Chloroplast                 site of cellular respiration, has 2 membranes                                                                                            Plasma membrane       selectively permeable                                                                                           Lysosomes                   Site of protein synthesis                                                                                           Ribosomes                   contains digestive enzymes

In addition to providing support, the cytoskeleton immobilizes enzymes and organelles in the cytoplasm. What advantage does this immobilization have over allowing the cellcontents to freely diffuse in the cytoplasm?

In what ways do the functions of the cytoskeleton differ from those of the endomembrane system?

Describe the general functions of the following in a eukaryotic cell: the plasma membrane, cytoplasm, DNA, ribosomes, organelles, and cytoskeleton.

What organelle provides energy for the cell in the form of ATP?

Shock (failure of the circulatory system) is an abnormal condition in which blood flow is inadequate. The most common causes of shock are massive blood loss and obstruction of blood flow. As a result of shock, there is a failure to provide cells with oxygen and nutrients. In this circumstance, cells swell and lysosomal membranes rupture, among other effects. Describe how energy is generated during shock and why cell structure becomes destabilized.
