| Question | Answer |
|---|---|
| the endoplasmic reticulum | has granular locations with ribosome attachments and is associated with protein synthesis |
| the golgi apparatus is associated with | packaging materials for transport |
| which one of the organelles is the site if the citric acid cycle? | mitochondria |
| the aerobic stage of energy production from carbohydrate, lipid, and protein catabolism involves | acetyl-co A, NAD and FAD, the citric acid cycle |
| the electron transfer chain is located in the | mitochondria |
| in the electron flow in the electron transfer chain | ATP is synthesized from ADP (oxidative phosphorylation), NADH and FADH2 are oxidized , oxygen is consumed and metabolic water is produced |
| a chromosome is | a large molecule of DNA |
| at which stage of mitosis is the nuclear envelope reconstructed? | telophase |
| mitosis? | is the division of somatic cells in which nuclear division precedes cytoplasmic fission |
| the sequence of bases on one strand of DNA is TGCCAT. what would be the sequence of bases of its complementary strand within a DNA double helix? | ACGGTA |
| during replication of DNA | the double helix is split and each nucleotide chain becomes paired with a new complementary strand forming 2 double helix chromosomes |
| the synthesis of a protein | occurs in the cytoplasm and us accomplished by RNA molecules |
| during the synthesis of protein | tRNAs, specific for each 20 amino acids, move to the cytoplasm to pick up respective amino acids and carry it to the mRNA where it is fitted into the code for a specific protein molecule |
| meiosis? | results in a reduction of chromosome numbers by one half (haploid or n) while still in the reproductive systems of the male and female |
| the nervous system develops from the germ layer known as? | ectoderm |
| the coelom is the forerunner of? | the pericardial, pleural, and abdominopelvic cavities |
| epithelial tissues are derived from? | ectoderm and endoderm |
| epithelium that appears to consist of many layers but actually only has one layer is known as? | pseudostratified columnar |
| glands with cells that accumulate secretory products in their cytoplasm and then die and disintegrate are known as? | holocrine glands |
| mucous membrane? | line the hollow organs and cavities that open on the skin surface of the body |
| tissues that produce intercellular substances (cartilage and bone) store fat, and produce various blood cells are known as | connective tissues |
| collagenous or white fibers, and elastic or yellow fibers | are intercellular substances produced by fibroblasts, are found in loose connective tissue, are found in dense connective tissue |
| within the head, rostral means? | towards the nose |
| a sagittal plane is | any plane parallel to the median line |
| the part of the limb, artery, or nerve that is nearest the center of the body or point of origin is referred to as | proximal |
| the position in which the dorsal aspect of the body or any extremity is uppermost is known as | prone |
| a mesentery is a connecting fold of the peritoneum that | attaches the intestine to the dorsal wall of the abdominal cavity |
| the mediastinum? | contains the heart, thoracic parts of the esophagus, trachea, vessels, and nerves |
| the serous membrane that lines the wall of the thoracic cavity is | parietal pleura |
| omentum refers to a peritoneal fold | passing from the stomach to other soft structure viscera |
