Flashcards in Lesson 3 Deck (28):
1

What does "lysis" mean?

to break

2

What happens during dehydration synthesis?

Bonds are created by removing water

3

What happens during hydrolysis?

Bonds are broken by adding water

4

What does it mean for a molecule to be organic?

It contains carbon atoms

5

What does two glucose molecules make?

Maltose

6

Disaccharide

made up of two molecules

7

In what form are sugars usually stored?

Polysaccharides

8

Why do carbohydrates have to be broken down into glucose by the body?

Mitochondria need glucose to produce energy for the body

9

Sucrose is made of what?

Glucose and fructose

10

What is a monosaccharide?

A single molecule of sugar, EX: glucose

11

How do monosaccharides combine to form polysaccharides?

By removing water (aka dehydration synthesis)

12

How is glucose different from glycogen?

Glucose is used first for quick energy, but glycogen is stored for when all the quick energy is used up

13

What two molecules combine to form molecules of fat?

glycerol and fatty acids

14

How are fats stored in the body?

As triglycerides

15

Which fats are the best for your health?

Monounsaturated

16

When are lipids (fat molecules) broken down into smaller molecules by your body?

During digestion and after you've used all of your quick energy

17

What process breaks up proteins so they can be used by the body?

Hydrolysis

18

What makes up proteins?

Amino acids

19

Function of vascular tissues in the plant?

Transport chemicals and water throughout the plant

20

What is produced through light reactions?

Oxygen, ATP, & NADPH

21

What organelle does photosynthesis occur in?

Chloroplasts

22

What are the three steps of cellular respiration?

glycosides, the Krebs cycle, electron transport chain

23

Purpose of cellular respiration?

to create energy from glucose

24

Where does glycolysis take place?

In the cytoplasm

25

Where do the Krebs cycle and electron transport chain occur?

The mitochondria

26

How many ATP molecules are produced for every glucose molecule during cellular respiration?

36

27

What does it mean to be 'anaerobic'?

Without oxygen

28

How many ATP molecules are produced for every molecule of glucose through cellular respiration?

2
