Energy and Enzymes
This molecule directly provides usable energy for cell processes.
What is ATP?
An organism with genotype Aa is described as:
What is heterozygous?
This hormone lowers blood glucose concentration.
What is insulin?
Organisms that make their own food are called:
What are autotrophs?
This macromolecule is made of amino acids.
What is a protein?
Enzymes lower this to speed up a reaction.
What is activation energy?
This process produces gametes with half the normal chromosome number.
What is meiosis?
The human body maintains stable internal conditions through this process.
What is homeostasis?
The original source of energy for most ecosystems is:
What is the Sun?
The monomer units of carbohydrates are called these.
What are monosaccharides?
The specific molecule an enzyme acts upon is called the:
What is the substrate?
Crossing-over occurs during this stage of meiosis.
What is Prophase I?
This organ filters blood and regulates water balance.
What is the kidney?
The maximum population size an environment can support is called:
What is carrying capacity?
This organic compound stores genetic information.
What is DNA?
This organelle is the site of aerobic cellular respiration.
What is the mitochondrion?
If two heterozygous parents are crossed, the probability of producing a homozygous recessive offspring is:
What is 25%?
During exercise, an increased breathing rate helps remove this waste gas.
What is carbon dioxide?
The increasing concentration of toxins at higher trophic levels is called:
What is biomagnification?
The element found in proteins but not always in carbohydrates or lipids is:
What is nitrogen?
At extremely high temperatures, enzyme activity decreases because the enzyme:
What is denatures?
A mutation that changes a DNA base but not the amino acid sequence is called this type of mutation.
What is a silent mutation?
This type of feedback mechanism reverses changes in internal conditions.
What is negative feedback?
When two different species compete for the same limited resource, the relationship is called:
This process converts the information in mRNA into a sequence of amino acids.
What is translation?
