Biology Questions 1-10

Question 1

What is an autotroph? (+Example)

Answer 1

an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

Example: a plant

Question 2

What is a Heterotroph? (+Example)

Answer 2

An organism deriving its nutritional requirements from complex organic substances.

Example: An animal - black bear

Question 3

Define Photosynthesis

Answer 3

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Question 4

What do ADP + ATP stand for?

Answer 4

ADP = Adenosine Di Phosphate

ATP =Adenosine Tri Phosphate

Question 5

What is the Difference between ADP + ATP?

Answer 5

• You get ADP by removing the 3rd Phosphate from ATP

- ADP looks almost identical to ATP, but it has 2 phosphate groups, instead of 3

Question 6

What is the fx of ATP in cells?

Answer 6

It stores and releases energy

Question 7

List 5 Activities that require ATP

Answer 7

• cell division.
• synthesis of proteins from amino acids.
• active transport.
• muscle cell contraction (in animal bodies)
• transmission of nerve impulses (in animal bodies)

Question 8

What are the 3 parts of ATP?

Answer 8

Adenine, Ribose, and Phosphate groups

Question 9

Write the equation for Photosynthesis?

Answer 9

6C02 + 6H20 + sunlight > C6H1206 + 602

Question 10

What are the reactants for Photosynthesis?

Answer 10

Water, light, carbon dioxide
