Photosynthesis
What is photosynthesis?
A process by which a cell captures energy in sunlight and uses it to make sugar (food).
What is cellular respiration ?
the process where cells breakdown food (glucose) in order to release energy ATP
What does it mean for the cell membrane to be semi-permeable?
It means that some molecules can diffuse across the cell membrane lipid bilayer but others cannot. In other words it can be very selective.
What are enzymes?
Enzymes are protein helpers that are used to perform metabolism, or the chemical reactions in our bodies.
What is osmosis?
The diffusion of water molecules from from HIGH to LOW concentration and requires no energy.
Where is the site of Photosynthesis?
Chloroplast
Where is cellular respiration takes place?
The Mitochondria !
What is the major difference between Solution, solute and solvent? Given an example!
A solution is a homogeneous mixture consisting of a solute dissolved into a solvent.The solute is the substance that is being dissolved, while the solvent is the dissolving medium.
Example: Salt is solute, Water is solvent, Salt water (saline) Solution.
Can an enzyme be used more than once during a chemical reaction?
Yes It can be used again as many times.
In what ways are photosynthesis and cellular respiration similar?
They both require ATP, they generate ATP, and they both involve inorganic and organic molecules.
list the two inorganic molecules that is required for plants in order to perform photosynthesis?
Co2 and H20
what are the two types of cellular respiration? Write their major differences as well!
Aerobic respiration which requires oxygen to breakdown glucose to create ATP. Aerobic respiration breakdown glucose to release energy but does not require oxygen at all
What are the three different types of way molecules can cross a cell membrane?
Diffusion, Facilitated Diffusion, and active transport
What do we call when an enzyme shape starts to unfold or breaking up?
Denature.
Why do you think plants have Stomatas? What is it purpose. Why do you think it opens and closes?
Stoma/Stomata- openings on the underside of leaf that lets molecules such as water vapor, oxygen, and co2 in and out. It also monitor how much light enters as well. Its there to maintain the plants homeostasis.
What are the two types of process of photosynthesis and their differences?
The light-dependent reactions requires light to create sugar; The light-independent reactions, or Calvin Cycle does not require light to make sugar.
What are the two types of fermentation reactions? Also write the type or organisms that uses this type of fermentation!
Alcohol fermentation: Yeast
Latic acid fermentation: Animals, bacteria
which of the types of diffusion is responsible for passive transporting larger or polar molecules through a protein channel
Facilitated Diffusion
What are the two factors that we investigated in the enzymes lab that had an affect on enzymes activity?
PH level and temperature.
What are the three types of effects of Osmosis on a cell?
Isotonic, hypotonic, and hypertonic
What is the equation for photosynthesis ?
6CO2 + 6H2O → C6H12O6 + 6O2.
What is the equation for photosynthesis?
C6H12O6 + 6O2→ 6CO2 + 6H2O
Which of the the types of diffusion requires energy? and why does it requires it?
Active transport requires energy because it`s uses a protein channel (pump) to move molecules against its concentration gradient.
What was the name of the enzyme that we were investigating during the Enzyme lab. Also what was the substance that it interact with? What was the substance broken down to?
catalase and breaks down hydrogen peroxide to water and oxygen.
Explain the cycle between photosynthesis and cellular respiration.
Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Plants products are glucose and Oxygen where its the reactants for cellular respiration. While cellular respiration products carbon dioxide and water are the reactants for photosynthesis.
