Intro to Biochemisry
This is what happens to the atoms in a chemical reaction, resulting in the formation of a new substance.
What is they get rearranged to form new molecules?
The process by which plants and algae use light energy to produce food.
What is photosynthesis?
This process breaks down glucose to release energy in the form of ATP.
What is Cellular Respiration?
Photosynthesis removes this gas from the atmosphere.
What is carbon dioxide?
This is the system used to grow algae for biofuel production.
What is a photobioreactor?
When baking soda reacts with vinegar in a closed container, this happens to the total mass of the system.
Chloroplasts in plant cells perform photosynthesis by converting light energy into this.
What is chemical energy (stored in glucose!)
The gas required by most organisms, including humans, to release energy from food.
What is oxygen?
The processes of photosynthesis and cellular respiration cycle this element through ecosystems.
What is carbon?
To measure density of algae growth, we can observe this about the water it is growing in.
What is the color? (darker green equals more algae!)
These are two examples of evidence that a chemical reaction has occurred.
What is
-Gas formed
-Color change
-Precipitate formed
-Temperature change
-Heat and light produced
-Properties of the substances change (new substance formed)
This molecule provides the carbon that plants use to form glucose during photosynthesis.
What is carbon dioxide?
Cellular respiration occurs in this organelle within cells.
What are mitochondria?
The movement of carbon through the atmosphere, organisms, and Earth’s systems is called this.
What is the carbon cycle?
In an experiment testing algae growth, the variable that is intentionally changed is called this.
What is an independent variable?
In the reaction HCl+Zn→H2+ZnCl2HCl + Zn, if the reactants have a mass of 100g, the mass of the products equals this.
What is 100g? (the mass of the reactants always equals the mass of the products!)
Photosynthesis produces this gas as a byproduct, which is essential for animal life.
What is oxygen?
Cellular respiration uses glucose and oxygen to produce these three products.
What are water, carbon dioxide, and energy (ATP)?
What are stomata in the leaves?
In an experiment testing algae growth, this is the variable which is measured to get the result of the experiment.
What is the dependent variable?
This law states the mass of the products in a chemical reaction is always equal to the mass of the reactants.
What is the law of conservation of mass?
This factor, when increased, often boosts the rate of photosynthesis until the other resources become limited.
What is light intensity?
Name one similarity and one difference between photosynthesis and cellular respiration.
What are both involve energy transformation (similarity), and one stores energy (photosynthesis) while the other releases it (respiration)?
This is how global temperatures have been changing due to the burning of fossil fuels.
What is they are rising?
In an experiment with algae growth, these are the variables that remain the same in each trial to ensure that the experiment is fair.
What are constant conditions?
