Photosynthesis
The primary organelle where light energy is absorbed and converted into chemical energy in eukaryotic plant cells.
What is the chloroplasts?
This organelle is responsible for the production of ATP.
What is the Mitochondria
This specific region on an enzyme molecule has a unique shape where substrate molecules bind to undergo a chemical reaction.
What is the active site?
The movement of solute molecules across a cell membrane from an area of high concentration to an area of low concentration without using metabolic energy.
What is passive transport
The process where membrane-bound vesicles fuse with the cell membrane to export waste products or secreted proteins out of the cell.
What is exocytosis
Photosynthesis transforms radiant energy from sunlight into this form of potential energy stored in the chemical bonds of glucose
What is chemical energy?
These two things are the reactants in cellular respiration
What is Glucose and Oxygen
Enzymes speed up metabolic reactions by lowering this specific threshold energy required to start a chemical reaction.
What is activation energy
The passive movement of water molecules across a selectively permeable membrane toward a higher solute concentration.
What is osmosis
Nerve cells send signals by releasing neurotransmitters. These molecules move out of the cell through the cell membrane and into the space between nerve cells. What process allows this to happen
Exocytosis
These things are the reactants of photsynthesis
What is Carbon Dioxide and Water
Cellular respiration transforms the potential chemical energy stored in the bonds of food into this usable chemical currency of the cell.
What is ATP
Because enzymes accelerate chemical reactions without being consumed or permanently altered, they fall under this chemical classification.
What is a catalyst?
Glucose and amino acids cross the cell membrane down their concentration gradient using transport proteins
What is facilitated diffusion
Unlike passive transport, active transport requires this cellular energy molecule to move substances against their concentration gradient.
What is ATP
What are the products of Photosynthesis
What is Glucose and Oxygen Gas?
What are the products of cellular respiration
What is Carbon Dioxide and water.
When extreme heat or severe pH shifts alter an enzyme's active site shape, rendering it nonfunctional, the enzyme has undergone this process.
What is denaturation?
This membrane protein actively pumps 3 sodium ions out of the cell and 2 potassium ions into the cell to maintain homeostasis.
What is the sodium potassium pump
What kind of biomolecules make up the cell membrane?
Proteins, Lipids, and Carbohydrates
Test Q:
Plants take in Carbon Dioxide from the air during photosynthesis. How are the carbon atoms conserved during this process?
Test Q:
During Cellular Respiration, oxygen molecules are used in the mitochondria. What happens to the oxygen atoms from these molecules
They are rearranged to form carbon dioxide and water
Test Q:
An enzyme has a region called the active site where the substrate molecule binds. What happens when the substrate fits correctly into the active site.
The substrate binds with the enzyme to form a new product.
When a red blood cell is placed in this type of solution, water leaves the cell via osmosis
What is a Hypertonic solution
When a patient comes to a hospital with severe dehydration, doctors will give them an IV filled with a salt-water solution called saline, which is isotonic with the body's blood cells.
Why is the patient not given pure water?
Pure water is hypotonic and would cause the patient's blood cells to swell and burst.
