Flow Chart What happens to food and energy when it enters the cell? Finish the description for each organelle. Step 1: Mitochond
torisob [31]

Explanation:

Eukaryotic cells have specialized mechanisms to transport molecules along with membrane-bound organelles like the endoplasmic reticulum that provide a higher surface area for absorption and enable more efficient transportation.

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. Several organelles facilitate the digestion of nutrients into metabolites and energy...

  • Step 1: Mitochondria break down food and release energy; In all eukaryotic cells mitochondria are small cellular organelles bound by membranes. The higher concentrations of reactants and solutes, increases metabolic reaction efficiency; these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is obtained via the breakdown of nutrients from food, and is stored within the molecule ATP. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate     (through the process of glycolysis in the cytoplasm) where several metabolites used for building other compounds are produced.
  • Step 2: Lysosomes... Some organelles separate proteins and molecules that may harm the cell by parceling them into membrane-bound organelles for example, proteases bound within lysosomes can break down many structural proteins, and carbohydrates found in food, waste, and cell components
  • Step 3: Vacuoles... Vacuoles are fluid filled organelles which store concentrated amounts of solutes, and waste products. Specialized vacuoles are also used to transport components to the cell membrane for cellular export.
  • Step 4: The endoplasmic reticulum... Most proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes in the rough endoplasmic reticulum. The rest of the ER, which does not contain ribosomes is called the smooth ER,  and may contain lipids,  enzymes, and other proteins. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.
  • Step 5: Golgi bodies... Like a post office, the golgi complex, or golgi body  recognizes signal sequences and packages these compounds into lysosomes for delivery to their final destination. Lysosomes fuse with the plasma membrane to empty their contents into the extracellular space.

Three factors that may have caused thirteen different species of finches to develop on the galapagos island
Oduvanchick [21]
From this one migrant species would come many -- at least 13 species of finch evolving from the single ancestor.
This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. The ecological niches exert the selection pressures that push the populations in various directions. On various islands, finch species have become adapted for different diets: seeds, insects, flowers, the blood of seabirds, and leaves.
The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters.
Scientists long after Darwin spent years trying to understand the process that had created so many types of finches that differed mainly in the size and shape of their beaks.
