Species
"Kids prefer candy over fresh green salads"
2. most abundant component of blood plasma is <Ans> water
3. typical magnification power of the ocular lens on a microscope <Ans> 10x
4. polarity is the most important characteristic of water because... <Ans> The
benefits of polarity are hydrogen bonding, a high specific heat value, strong
cohesive and adhesive properties, and its versatility as a solvent
5. All of the activities that occur within a cell are dependent on the presence
of which of the following components? <Ans> water
,6. Carbohydrates are made up of <Ans> carbon, hydrogen, oxygen
7. a lipid that is a component of cellular membranes and a precursor to
significant hormones and drugs <Ans> steroids
8. difference between saturated and unsaturated fats <Ans> Unsaturated fats
contain one or more double bonds in their hydrocarbon tail, while saturated fats
contain no double bonds.
9. Which biologic molecule would you recommend a patient limit if they want
to avoid having cardiovascular problems? <Ans> saturated fats
10. Polymers of which of the following make up proteins <Ans> amino acids
11. three types of lipids <Ans> fatty acids, phospholipids, and steroids
12. Which of the biologic molecules are considered the most significant when
it comes to contributing to cellular function? <Ans> proteins
13. How are carbohydrates absorbed into the bloodstream? <Ans>
Carbohydrates are turned into glucose and absorbed into the blood via the walls of
the small intestine
14. Essential amino acids <Ans> amino acids that cannot be naturally
produced by the body and, therefore, are obtained through the organism's diet
15. Nonessential amino acids <Ans> amino acids that can be made by the
human body, so they are not essential to the human diet
,16. 2 main functions of steroids <Ans> important parts of cell membranes and
they act as signaling molecules
17. In a cell, reactions take place in a series of steps called <Ans> metabolic
pathways
, 18. third step of cellular respiration. This step begins with the oxidation of
NADH molecules to produce oxygen and finally to produce water <Ans>
electron transport chain
19. catabolic pathway (a set of metabolic reactions and processes) that takes
place in cells and results in energy production for the cell <Ans> cellular
respiration
20. Metabolic reactions in a cell progress from a standpoint of <Ans> high
energy to low energy
21. The sum of all chemical reactions that occur in an organism is <Ans>
metabolism
22. The smooth endoplasmic reticulum is responsible for <Ans> storing
calcium ions
23. found in animal cells but not plant cells <Ans> centrioles
24. What function do cholesterol molecules serve within the cell membrane?-
<Ans> They stabilize the flexible bilayer structure to prevent breakage
25. Although animal cells lack cell walls, they do have an elaborate system of
glycoproteins that provide support to the outside of the cell called the
<Ans> extra- cellular matrix
