Cellular Respiration
What gas do we need to breathe in for cellular respiration to make the most ATP? Part two. What gas do we need to get rid of, because it is a byproduct of cellular respiration?
what is Oxygen. part 2 What is Carbon Dioxide (CO2)
What is the gas plants need for photosynthesis? Part 2. Where does it enter the plant?
When does lactic acid fermentation occur in human cells?
What is when oxygen is not available (anaerobic conditions, like during intense exercise)?
Which process releases carbon dioxide into the atmosphere when organisms break down glucose for energy?
What is cellular respiration?
In the movie Finding Nemo, Marlin and Dory travel through a field of jellyfish. Jellyfish don’t have lungs — how do they get the oxygen they need for respiration?
What is diffusion directly through their skin?
What is the starting molecule of glycolysis (the first stage of cellular respiration)?
Glucose
What are the two main stages of photosynthesis?
What are the light-dependent reactions and the Calvin cycle?
What causes muscles to feel sore after hard exercise?
What is the buildup of lactic acid in the muscles? That is why it is called lactic acid fermentation.
Which process removes carbon dioxide from the atmosphere and stores it in glucose?
What is photosynthesis?
In Wall-E, Earth has very few plants left. If photosynthesis stopped globally, atmospheric carbon dioxide levels would rise. Explain how this would affect both climate and the process of cellular respiration in humans and animals.
What is CO₂ would build up causing climate change, while O₂ would decrease, limiting cellular respiration in organisms? It would support a lot less organisms.
What is the organelle that cellular respiration takes place in (for the most part)?
What is Mitochondria. but glycolysis starts in the cytoplasm (which is good because there are bacteria that do not have mitochondria)
In which part of the chloroplast do the light-dependent reactions occur?
What is the thylakoid membrane?
What are the main reactants and products of lactic acid fermentation?
Reactant: glucose → Products: lactic acid + 2 ATP
How does carbon dioxide move between the atmosphere and the ocean?
What is diffusion (CO₂ dissolves into and out of ocean water)?
Astronauts on the ISS grow plants to recycle air. Besides releasing oxygen, what other role do plants play in balancing gases for the crew, and how does this connect to the carbon cycle?
What is plants take in CO₂ from astronaut respiration, preventing dangerous CO₂ buildup, and store it as sugars in the carbon cycle?
What are the products and reactants of cellular respiration?
Reactants are Oxygen and Glucose
Products are Carbon Dioxide, Water, and ATP
What is are the products and reactants of photosynthesis?
Reactants are Water, Carbon Dioxide, and sunlight
Products Glucose and Oxygen
What are the products of alcoholic fermentation, and what is one real-world use?
Products: ethanol + CO₂ + 2 ATP; Real-world use: bread rising or brewing alcoholic drinks
How do forest fires affect the carbon cycle?
What is burning plant matter and releasing stored carbon as carbon dioxide into the atmosphere?
Destiny the whale shark is enormous and needs lots of energy. Compare the efficiency of aerobic cellular respiration in Destiny’s cells to anaerobic respiration — why would anaerobic respiration not sustain such a large animal for long?
What is aerobic respiration produces ~36 ATP per glucose, while anaerobic makes only 2 ATP, far too little to fuel a whale shark’s energy needs?
Per glucose molecule, about how many ATP molecules are generated in aerobic respiration compared to anaerobic fermentation?
What is about 36–38 ATP in aerobic vs. 2 ATP in anaerobic . Or A LOT MORE
Draw a chloroplast organelle and label the thylakoid, stroma, and indicate where the chlorophyll is located.
Correct drawing with correct labels.
Compare the ATP yield of fermentation (no oxygen, anaerobic) to aerobic (with oxygen) respiration.
What is 2 ATP per glucose in fermentation vs. about 36 ATP per glucose in aerobic respiration?
A tree in a forest uses photosynthesis to store carbon in its wood. After the tree dies, explain two different ways this carbon could continue cycling — one pathway that releases carbon back into the atmosphere, and one pathway that stores it in a reservoir.
What are (1) decomposition and respiration by microbes releasing CO₂ into the atmosphere, and (2) burial of plant material where it can become fossil fuels or soil organic matter, storing carbon in a reservoir?
