100

In a typical single graph, which axis would you place the independent variable on?

x-axis

100

Which biomolecule is made up of the elements CHONP

Nucleic Acids

100

Distinguish one difference between eukaryotic and prokaryotic.

Eu = true nucleus, membrane bound organelles

Pro = no nucleus

DNA structure/location

100

What day is your final?

1st = Friday

2nd = Monday

4th = Tuesday

6th = Wednesday

100
Which type of organisms to photosynthesis and cellular respiration?

Plants

200
In detail, how would you describe to someone what the constant of an experiment is?

The variable(s) that are kept the consistent throughout the entire experiment.

200

What are the building blocks for lipids?

Fatty acids (+ glycerol)

200

This organelle is responsible for the production of proteins.

Ribosome

200

What 3 things is an ATP molecule made up of?

Adenine, Ribose sugar, and 3 phosphates

200

State the equation for cellular respiration

C6H12O6 + 6O2 = 6H2O + 6CO2 + ATP

300

Define homeostasis

Maintaining a stable internal environment

300

Give an example of a carbohydrate and a nucleic acid.

Glucose/Fructose/Lactose

DNA/RNA

300

Define selectively permeable. 

Only allows certain material into the cell while keeping other material out.

300

Which color light(s) do plants perform photosynthesis the most rapidly?

Red, Blue

300

In which organelle does photosynthesis occur in?

Chloroplast

400

Describe the difference between heterotroph and autotroph.

Autotroph - self feeder (makes its own energy) typically producers


Heterotroph - obtains food/energy from another source, doesn't make its own food.

400

What is the function of lipids?

long term energy storage, insulation.

400

If a cell is made up of 58% water, and is soaking in a solution made up of 97% water. Which direction will water be moving, what will happen to the size of the cell, and what tonicity (hyper/hypo/iso)

Water moves into the cell, grows, hypotonic

400

Put in order from smallest to largest:

organ, organelle, cell, organism, tissue, organ system

organelle, cell, tissue, organ, organ system, organism

400

Describe how/where energy is released from an ATP molecule.

When the bond is broken between the 2nd & 3rd phosphate energy is released, ATP then becoming ADP.

500

Name 6 of the 8 characteristics of life

Homeostasis

Responds to environment

Obtains/uses energy

Growth/Development

Made of cells

Adapt over time

Reproduce

Universal genetic code

500

Describe why the enzyme lactase is so specific and only works on lactose.

The enzyme substrate complex is like a lock and key mechanism. Specific enzymes will only break apart specific substrates, in this case breaking down lactose into glucose & galactose.
500

List 2 components of the cell membrane and state their function. 

Phospholipids - protection of cell contents, packed closely together, allows small objects to enter/exit cell, functions as a barrier

Cholesterol - flexibility of membrane, prevents phospholipids from sticking together

Carbohydrate chain - cell to cell recognition (identify harmful cells)

Transport proteins - pass large material from one side of the cell to the other

500

What is an isotonic solution?

Concentration of water/solute inside the cell is equal to the concentration of water/solute outside (surrounding) the cell.

500

What are the two types of fermentation and are they aerobic or anaerobic?

Alcoholic, Lactic Acid

Anaerobic
