Metabolism Energy
What is ATP?
The energy of cells
What are enzymes?
are molecules that speed up chemical reactions
without being affected by the reaction. Usually, they are proteins.
What is Cellular Respiration?
The process cells acquire energy by
breaking down organic molecules.
Define Photosynthesis
Photosynthesis is the process by solar energy converts carbon dioxide into carbohydrates.
What is the largest planet in the solar system?
Jupiter
What type of energy is stored energy in a potentially usable form?
Potential energy
What are RNA molecules that act as enzymes and can catalyze chemical reactions called?
Ribozymes
What does NAD stand for?
nicotinamide adenine dinucleotide
What are Heterotrophs?
are organisms that cannot synthesize organic
compounds and must take in organic food.
What is the hardest natural substance in the world?
Diamond
Define Entropy
The measure of disorder or randomness in a system.
What does Optimal pH do?
increases the reaction rate of
enzymes
What is the difference between Aerobic and Anaerobic?
Aerobic are chemical processes that require oxygen. Anaerobic are chemical processes that do not require oxygen.
What do Carotenoids do?
Absorb violet and blue green, so it appears yellow
and orange.
The Femur
What is free energy?
The amount of energy left to do work after a chemical reaction.
True or False, Enzymes have active sites
where substrates attach.
True
What does Glycolysis mean?
Glycolysis means sugar-splitting
What are the 3 pigments the chloroplast has?
Chlorophyll a(light capturing
pigment directly involved in light
reactions ),Chlorophyll b( transfers energy to
chlorophyll a), and Carotenoids(an accessory
pigment).
What is the name of the desert that covers much of northern Africa?
The Sahara Desert
What is the difference between Exergonic and Endergonic reactions?
Exergonic Reactions are spontaneous reactions that release energy while endergonic reactions require an input of energy for reaction to occur
When does Enzyme Inhibition Occur?
When a molecule binds to an enzyme and
decreases its activity.
What are the phases of Cell Respiration?
Glycolysis, preparatory reaction,Citric Acid Cycle, and Electron Transport Chain
What two photosystems are light reactions separated into.
Photosystem I (PS I) and Photosystem II (PS II)
What is the largest mammal in the world?
Blue Whale.
