This type of bulk transport moves large substances out of the cell

Exocytosis

What is cellular respiration?
Breaks down food molecules to release stored energy.

What are all living things made of?
Cells

What is the single unit (monomer) that DNA is made up of?
Nucleotide
200

What type of transport moves molecules from a high concentration to a low concentration and requires a protein for assistance?

Active Transport

Why do plants appear green?
Plants reflect green light so your eyes see green. Plants absorb red and blue.
200

Name on property of water that supports a characteristic of life

High heat of vaporization Cohesion & Adhesion High specific heat More dense as solid than liquid Universal Solvent

200

What are the characteristics of life?

Made of cells Have DNA and RNA Grow and develop Obtain and use energy Ability to reproduce Responds to environment Adapts

300
What are the three parts of a nucleotide?
Sugar, Phosphate, and Nitrogen Base
300
What happens to a cell in an isotonic solution?
The cell stays the same
300
What is lactic acid fermentation and when does it happen?
Lactic acid fermentation is the breakdown of glucose without the use of oxygen. It creates lactic acid as a product. It happens in the muscles when we work them too hard and there is not enough oxygen present to perform cellular respiration.
300

Ammonia (NH3) has what type of bonds between N and H?

Polar covalent bonds

300
What is the difference between growth and development?
Growth is getting larger or taller; development is a cycle of change
400

What type of biological molecule is most abundant in the plasma membrane?

Lipids (Phospholipids)

400
What happens to a cell in a hypotonic solution? What happens to a cell in a hypertonic solution?
Hypotonic - the cell gets larger Hypertonic - the cell shrinks
400
Where in the cell does photosynthesis take place? Where in the cell does cellular respiration take place?
Photosynthesis: Chloroplast Cellular Respiration: Mitochondria

Give an example of an ionic bond

Na+ Cl-; or others

400
Define and give an example of homeostasis?
Homeostasis is maintaining an internal environment. Getting a fever when you are sick is an example.
500

What type of bonds hold together secondary protein structure?

Peptide Bonds - Primary structure; Hydrogen bonds - Secondary structure

500

What are the two types of transport that need proteins?

Facilitated diffusion; active transport

500
What are the reactants and product of photosynthesis and cellular respiration?
Photosynthesis: Carbon dioxide + Water + sunlight ----> Oxygen + glucose (Reactants) (Products) Cellular Respiration: Oxygen + Glucose ->Carbon dioxide +Water+Energy (ATP) (Reactants) (Products)
500

What type of bond has equally shared elections? 

Polar covalent bond

Give an example of each characteristic of life.
Growth and development - getting taller Based on a genetic code - organisms have DNA Made of cells - we are made of billions of cells; bacteria are unicellular. Ability to reproduce - a dog had five puppies Responds to environment - Jumping when you hear a loud noise. Shivering and sweating. Evolves - finches changing over time to adapt to different food. Obtain and use energy - eating a sandwich
