Water & Molecule
What two elements make up a water molecule?
Hydrogen and oxygen
What is the main energy-carrying molecule in cells?
ATP
What is the main energy source for photosynthesis?
Sunlight
What is an enzyme?
A biological catalyst that speeds up a chemical reaction
Which biomolecule is made from amino acids?
Proteins
Who's Mr. Amen's favorite Star Wars character?
Baby Yoda
What does it mean when a molecule is polar?
It has an uneven distribution of electrical charge
What happens when ATP loses a phosphate group?
It becomes ADP and releases usable energy
Name one product of photosynthesis
Glucose or oxygen
What does an enzyme do to activation energy?
It lowers activation energy
What three elements are found in glucose?
Carbon, hydrogen, and oxygen
What's Mr. Amen's other job?
Tieling
What property of water helps it stick to the walls of plant vessels?
Adhesion
What is the main purpose of cellular respiration?
To transfer energy from glucose into ATP
What gas do plants take in during photosynthesis?
Carbon dioxide
Are enzymes used up during the reactions they help?
No they are not consumed
Which type of molecule forms much of the cell membrane's double layer?
Phospholipids
How big is Mr. Amen's forehead?
TOO BIG
How many bonds can one carbon atom form?
Up to four bonds
How does energy from the Sun eventually help animals power their cells?
Plants use sunlight to make glucose, which animals get from food to produce ATP
Name two inputs of cellular respiration
Glucose and oxygen
Why might an enzyme stop working properly at very high temperatures?
Its shape can change, affecting how it works
What is the difference between passive and active transport?
Passive transport does not require cellular energy; active transport does
Who does Mr. Amen dress up as for Halloween every year?
Ted Lasso
Why can water dissolve many polar substances?
Its positive and negative ends attract other polar molecules and ions
What does conservation of mass mean during a chemical reaction?
Atoms are rearranged, but the total mass stays the same
How are photosynthesis and cellular respiration connected?
Photosynthesis stores energy in glucose, while cellular respiration uses glucose to make ATP
How does an enzyme help a reaction happen faster?
It lowers the activation energy needed for the reaction
Why can't cells build nucleic acids using only sugars?
Nucleic acids also need nitrogen-containing bases and phosphate groups
What is Mr. Amen's full name?
Kurt Robert Amen
