Flashcards in Exam 1- Chemistry Deck (13):
1

DNA

Deoxy-ribose nuclei acid
Cytosine binds to guanine
Adenine binds to thymine

2

Cellular respiration equation

glucose + oxygen + energy carrier -> carbon dioxide + water + energy carrier

3

ATP

Adenosine- triphosphate

Energy released from breaking of covalent bonds in glucose during respiration is captured, stored and transported by ATP

4

Acids

Donate or give away hydrogen ions

5

Bases

Accept or receive hydrogen ions

6

Buffers

Resist changes in cells pH by releasing or accepting free hydrogen ions

7

Low pH

Acid( eg lemon juice and stomach acid= 2)

8

Neutral pH=

7 (eg distilled water, blood)

9

High pH

Basic (eg oven cleaner 13.5)

10

pH

Is the scale that the amount of H+ is measured by (0-14)

11

Proteins

Large molecules composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for protein. They are required for the structure, function and regulation of the body's cells, tissues, and organs.

12

Phospholipids

Are vital as they form the barrier between the cell and external environment. Materials that dissolve in lipid can pass through readily

13

RNA

Single strand
