Macromolecules
Name the four major macromolecules and list their elements!
What are CARBOHYDRATES CHO (1:2:1), LIPIDS CHO, PROTEINS CHON, NUCLEIC ACIDS CHONP
A biological catalyst that speeds up chemical reactions
What is an ENZYME
What is GLUCOSE and OXYGEN
What are the products of cellular respiration?
What is CARBON DIOXIDE, WATER, and ATP (energy)
What is an ATP molecule?
ATP is a chemical compound cells use to store and release energy.
This macromolecule is the main source of energy for all living things.
What is CARBOHYDRATE
How do pH and temperature affect the function of enzymes?
DENATURE! They change their shape and are unable to function
What are the reactants of photosynthesis?
What is WATER and CARBON DIOXIDE
What are the reactants of cellular respiration?
What is OXYGEN and GLUCOSE
Type of transport that requires energy
active transport
This macromolecule stores energy and forms biological membranes.
What is LIPID
Draw a cell in a hypertonic solution.
should show more salt outside cell which would cause water to leave and cell to shrivel
What do plants need to get the process of photosynthesis going?
What is SUNLIGHT
Cellular respiration is considered AEROBIC because _________
draw how molecules move during ACTIVE transport.
should show molecules moving against concentration gradient.
This macromolecule stores and transmits genetic information
What is NUCLEIC ACID
If a cell is placed in a mysterious solution and it causes the cell to swell. What type of solution is it in?
Openings in leaves that allow for gas transfer
stomata
Cellular respiration is energy _______ reaction.
What is RELEASING
How do simple diffusion and facilitated diffusion differ? list one type of molecule that moves each way.
This macromolecule regulates cell processes, controls the rate of reactions, moves substance into or out of cells.
What is PROTEIN
Enzymes function as catalysts to do what?
lower activation energy for reactions
How can we measure the rate of photosynthesis?
recording oxygen production
What are the two types of anaerobic respiration?
What are alcoholic fermentation and lactic acid fermentation.
How do cellular respiration and photosynthesis connect to the carbon cycle?
Both move carbon around in various forms (making/breaking down glucose and absorbing and releasing CO2)
