mitochondrion D) Golgi apparatus LI peroxisome 17) Which organelic is the primary site of ATP synhesis in eukaryotic cells? A) lysusonc B) vacuole miochondion DD) Golgi apparatus E) peroxisome 1S) Motor proteins provide for moecular motion in cells by interacting wirh whar types of celular structures? A) sites of encrgy production in celiular rospiration B) membrane proteins C) ribnsomcs Drcyloskeletal structures F) celiulose fibers in the cell wal 19) Which structure is not part of the endomembrane system? A) nuclear envelope Brchloroplast C) Golgi upparatus D) plasma membrane E) ER 20) Which structure-function pair is misoutchod A) nucleolus; production of ribosomal subunits B) lysosome; intracellular digestion C) ribosome; protein synthesis D) Golgi; protein trafficking nicrotuhule; muscle contraction 21) The presence of cholesterol in the plasma membranes of some animals enables the membrane to stay fluid more easily when cell temperature drops B) enables the animal to remove hydrogen atoms from saturated phospholipids.Explanation / Answer
Answer:
17). C. Mitochondria
Explanaiton: Cellular respiration is process of ATP synthesis, which occurs in mitochondria.
18). D. Cytoskeleton structures
Explanation:
Three main structural components of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three components interact with each other non-covalently.
19). B. Chloroplast
Explanation:
In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane, among others.
20). E. Microtubule; muscle contraction
Explanation:
Microtubules serve a transportation function, as they are the routes upon which organelles move through the cell.
21). A) enables the membrane to stay fluid more easily when cell temperature drops.
