What is an autotroph?
use energy from the sun or chemicals to make organic compounds
What is a heterotroph?
animals that must get energy from food
What do all cells need? hint: cellular energy
All cells need chemical energy
What is photosynthesis?
Plants absorb energy from sunlight
What is cellular respiration?
Cells break down sugars to produce usable chemical energy for their functions
Do energy drinks or power bars do something different from any other foods you eat?
They may contain certain types of carbohydrates that can be used more quickly and so supply energy faster.
What organelle is involved in photosynthesis?
Chloroplast
What organelle is involved in cellular respiration?
Mitochondria
This molecule transfers/carries energy. It has THREE phosphate groups.
ATP
This molecule transfers/carries energy. It has TWO phosphate groups.
ADP
This molecule transfers energy from the breakdown of food molecules to fuel all cellular functions
ATP
X is changed into Y when a phosphate group is added. What is X and Y?
ADP to ATP
Foods that you eat do NOT contain ATP. Is this true or false?
True
Food must be digested, which breaks down food into smaller molecules that can make ATP. Is this true or false?
True
Which macromolecule stores the most energy? Carbohydrates, Proteins, or Lipids?
Lipids (fats)
What macromolecule is LEAST likely to be broken down to make ATP?
Proteins are least likely to be broken down to make ATP.
