Being made up of multiple cells Cycles of consciousness and sleep The ability to grow and reproduce Division into multiple sexes CONCEPT Organisms 3 What is true about the electron transport chain (ETC)? The electron transport chain is the second stage of cellular respiration. During the electron transport chain, a hydrogen gradient is produced that is used to produce ATP from ADP. The electron transport chain produces 36 net molecules of ATP. The largest byproduct of the electron transport chain is carbon dioxide. CONCEPT Electron Transport Chain 4 Which of the following is present only in RNA? Uracil Cytosine Guanine Adenine CONCEPT Nucleic Acids 5 Which of the following is a characteristic of the plasma membrane? It allows some molecules to pass through but prevents others from doing so. The outward facing phospholipid tails give it a rough quality. It is made up of one layer of phospholipids. It doesn't contain any molecules aside from phospholipids. CONCEPT Plasma Membrane 6 Which of the following statements about enzymes is true? Enzymes can only break down larger substances into smaller ones. Enzymes are composed primarily of carbohydrates. The function of an enzyme is to speed up chemical reactions that occur in your body. Enzymes are single-use proteins that must be regenerated after each reaction. [Show More]
