Flashcards in Extra Info Deck (26):
1

What are molecules that influence the rates of chemical reactions but are not consumed in the process

Catalysts

2

What is a chemical bond between atoms that shares electrons

Covalent

3

The attraction of positive hydrogen end of a polar molecule to the negative nitrogen or oxygen end is called what?

Hydrogen bond

4

What are positively charged ions?

Cations

5

What are negatively charged ions

Anions

6

what are chemicals that resist PH change

Buffers

7

Solutions with more hydrogen ions that hydroxide ions are considered what

Acidic pH values less than 7.0

8

Solutions with fewer hydrogen ions than hydroxide ions are what

Basic (alkaline) pH greater than 7

9

What are some inorganic molecules

Water. Oxygen. Carbon dioxide.

10

What is the main difference between organic and inorganic substances.

Inorganic dissolve in water and disassociate, forming ions. Organic mostly dissolve in alcohol, the ones that do dissolve in water don't realize ions.

11

What is a polysaccharide abundant in plants?

Cellulose

12

What do humans synthesize that is similar to starch?

Glycogen

13

What are the building blocks of fat molecules?

Fatty acids and glycerol

14

What is fatty acids is when single carbon atoms bind as many hydrogen atoms as possible?

Saturated

15

What's the difference between saturated and Unsaturated fats

Saturated are more abundant in fatty solid food. Unsaturated are in foods that are liquid at too temp.

16

What are the most heart healthy fats

Monounsaturated

17

What process produces trans fats

Hydrogenation

18

What proteins carry oxygen in the blood and muscles

Hemoglobin and myoglobin

19

What are enzymes

Catalysts in living systems; speed chemical rearixons without being consumed

20

What lipid is connected by 4 rings of carbon?

Steroids is

21

What lipid is three fatty acid molecules bound to a glycerol molecule

Triglycerides

22

What is the name given to cells with nuclei

Eukaryotic "true nucleus"

23

What name is given to cells of bacteria

Prokaryotic

24

Name some biochemical reactions from peroxisomes

Synthesis of vile acids in fat disgetion. Breakdown of lipids called very long cabin fatty acids. Degradation of rare biochemicals. Detox of alcohol. Form phospholipids of nervous system

25

When can diffusion only occur

If the cell membrane is permeable to that substance and a concentration gradient exists such that the substance is at a higher concentration on one side of the membrane or the other

26

What form of movement through the cell does HIV use

Transcytosis
