Cellular Respiration Cellular respiration refers to the chemical reactions that break down glucose to CO 2 and H 2 O, releasing the energy stored within its bonds. The energy is temporarily stored in the bonds of ATP (adenosine triphosphate). ADP + P i + energy ATP This process requires oxygen in aerobic organisms. Anaerobic organisms do not require oxygen, but produce much less ATP per glucose molecule. Aerobic cellular respiration occurs in the mitochondria . Prokaryotes do not have mitochondria.

The cristae that project into the gel-like matrix. Enzymes involved in cellular respiration are found in the matrix and embedded in the membrane of the cristae.

Unformatted text preview: Cytoskeleton The cytoskeleton is a network of protein elements that extend through the cytoplasm in eukaryotic cells. It provides for the distinctive shape of cells such as red blood cells , muscle cells , and nerve cells (neurons). It produces movement of cells and is associated with movement of materials within cells. It is composed of three types of protein fibers: microtubules , actin filaments , and intermediate filaments . The general function of each of these is listed in the table below. Cytoskeleton Element General Function Microtubules Move materials within the cell Move the cilia and flagella Actin Filaments Move the cell Intermediate Filaments Provides mechanical support...
