what is a nucleus?

- control center

- contains DNA

100

What are the macromolecules?

- Protein

- Lipid 

- Carbohydrate 

- Nucleic Acid

 

100

What is an example of Carbs?

- bread

- sugar

- starches 

100

finish the sentence

Water is held together with covalent bonds between...

2 hydrogen atoms and 1 oxygen atom.

100

What is Adhesion? 

it is when water sticks to other substances

200

What is a mitochondria?

- Powerhouse of the cell

- the mitochondria provides ATP to the cell

200

What are the 3 Basic structures of a Nucleic Acid?

1. Sugar

2. phosphate group

3. nitrogen base

200

What are the 4 main functions of lipids?

- store energy long term 

- makes up cell membrane 

- hormones

- insulator

200

Why is water polar?

because the oxygen atom is slightly negative and the hydrogen atoms are slightly positive making it so they can attract both charges

200

What is pH?

pH helps us determine whether a solution is acidic, basic, or neutral. 

300

What is a Chloroplast?

- converts solar energy into chemical energy
300
What are the building blocks of a lipid?

Fatty acid and bonus Glycerol

300

Do Carbs store energy long term or short term?

Short term

300

True or False

Water can dissolve EVERYTHING.

False

It can dissolve polar molecules

300

What does RNA stand for?

Ribonucleic Acid

400

What is a Ribosome?

- synthesizes protiens 

400

What are Monosaccharides?

- simple sugars

- building blocks for carbs

400

True or False

A neutral pH is in the range of 6-8

false 

extra credit: what is neutral PH?

400

How can water form dome like shapes when on a surface?

Cohesion

400

How can you determine if something is an enzyme?

if it has ASE at the end 

ex: lipase 

500

What is a Endoplasmic Reticulum? 

- internal membrane system 

- assembles proteins and lipids


500

What is the importance of an enzyime?

speed up chemical reaction by:

- breaks molecules apart

- bringing molecules together

Enzymes lower the activation energy of the reaction that needs to take place



500

Define macromolecule 

a large molecule that is made of a chain of smaller molecules. 
500

How does water use Capillary Action?

water moves upwards from plants roots to plants leaves.

Bonus - how does water do this (hint: use the words Cohesion and Adhesion)

500

What is a Chemical Reaction?

When the reactants are changed into one or more different products
