Transport
The movement of particles from areas of higher concentration to lower concentration is called this
What is diffusion?
Enzymes are mostly made of these macromolecules
What are proteins?
A change in environmental conditions is referred to as this
What is a stimulus?
These tiny openings on leaves open and close to control gas exchange.
What are stomata?
Burning coal, oil, and natural gas releases this gas into the atmosphere
What is carbon dioxide?
Referred to as "the powerhouse of the cell", this organelle is where cellular respiration is performed
What is the mitochondria?
Chromosomes, made of DNA and proteins, are structures that carry this
What is genetic material?
The movement of water across a selectively permeable membrane from an area of high water concentration to low water concentration is called this
What is osmosis?
In an enzyme-catalyzed reaction, the enzyme binds to these molecules and transforms it into these molecules
What are substrates and products?
This organ helps regulate blood sugar by releasing insulin
What is the pancreas?
This plant tissue carries water and minerals upward from the roots to the leaves
What is the xylem?
The burning of fossil fuels, deforestation, and industrial activities contribute to this global phenomenon
What is climate change?
This organelle is where photosynthesis takes place
What is the chloroplast?
This type of RNA carries genetic information from DNA to the ribosome for protein synthesis
What is mRNA?
A solution with a higher concentration of solutes than the cell is called this
What is hypertonic?
This is the specific region of an enzyme where the substrate binds
What is the active site?
Negative feedback mechanisms maintain dynamic equilibrium by...
What is detect changes and send signals to help the body return to a stable, balance state?
This process describes the loss of water vapor from a plant's leaves
What is transpiration?
Oceans and forests act as this type of carbon reservoir, absorbing carbon dioxide from the atmosphere
What is a carbon sink?
Needed for photosynthesis are these 3 ingredients
What are sunlight, carbon dioxide, and water?
DNA is made up of these building blocks, which include a sugar, a phosphate group, and a nitrogenous base
What is a nucleotide?
Osmosis occurs across this type of membrane that allows some substances to pass but blocks others
What is a selectively permeable membrane?
Enzymes speed up chemical reactions by lowering this
What is activation energy?
This system works with the nervous system to release hormones that help maintain homeostasis
What is the endocrine system?
Phloem mainly transports this kind of molecule produced during photosynthesis
What is glucose?
Oceans help reduce atmospheric carbon by absorbing it, a process which can lead to this problem if carbon levels get too high
What is ocean acidification?
Producers at the base of every food chain are known by this term
What is autotroph?
In DNA, adenine pairs with this base whereas in RNA is pairs which this base
What is thymine and uracil?
This happens to animal cells will burst when placed in this type of solution
What is hypotonic?
This happens when the temperature gets too high and substrate can no longer bind with the enzyme
What is denaturation?
Water sticks to itself for this reason
What is its polarity? Water is a polar molecule.
During transpiration, this is how plants demonstrate negative feedback
What is open the stomata where there is high water content in the plant and close the stomata when the water levels in the plant are low?
This technology aims to artificially capture carbon dioxide from the air and store it underground to combat climate change
What is carbon capture and storage (CCS)?
The energy released from ATP is done by this
What is hydrolysis?
OR
What is breaking the bond between the 2nd and 3rd phosphate groups?
RNA differs from DNA because it is single-stranded and contains this sugar
What is ribose?
