Unit 2: Cell Energy
Sunlight, carbon dioxide, and water are required for photosynthesis. Examine the graph. What is the best explanation for the relationship between light intensity and the rate of photosynthesis.
As light intensity increases, the rate of photosynthesis increases until photosynthesis reaches its maximum rate. Explain: The photosynthesis stopped and continued in a straight line meaning that it had a limit.
Your body needs a constant supply of oxygen for cellular respiration to produce the ATP needed to fuel your body processes. When you exert yourself in a strenuous workout the oxygen demands of your muscle cells quickly outpace the oxygen your body can provide. Skeletal muscle cells that have an insufficient oxygen supply to allow aerobic respiration to continue will undergo lactic acid fermentation. Refer to the model above. Predict what changes will occur when your body shifts from aerobic respiration to anaerobic respiration (lactic acid fermentation). Select ALL that apply.
Cells produce less ATP. Lactic acid is produced as a byproduct. Explain: anaerobic
Matter constantly cycles through the earth's spheres using many different processes. Photosynthesis and cellular respiration are two important processes in this cycling of matter. The products of photosynthesis are reactants in cellular respiration. The products of cellular respiration are the reactants of photosynthesis. This model shows the cycling of matter through these cycles. The model is unlabeled. Correctly label the products and reactants of cellular respiration. Choose ALL three that apply.
D = O2 + C6H12O6 A = ATP B = CO2 + H2O Explain: Formulas found in our packets
The by-products of cellular respiration include
carbon dioxide and water Explain. This is what they take in so that they can start the reaction to create or take out carbon dioxide and their other products.
Producers, like this plant, take in oxygen and release carbon dioxide during __________________ , just like animals and other living things.
cellular respiration. Explain: Not Photosythesis
Photosynthesis is used to produce food for plants. Plants are called autotrophs because they produce their own food. Animals are heterotrophs, meaning they eat their food. What do plants produce in photosynthesis that is used by animals and other heterotrophs?
glucose and oxygen Explain: these are the products of photosynthesis
During winter, what factors can reduce the rate of photosynthesis in evergreens such as pine trees? Choose ALL that apply.
less sunlight Explain: I thought i hit this answer choice so idk how it was wrong... and it said choose all that apply insinuating there is more than one answer...
The chemical process for respiration
releases energy. Explain: I did not find notes that matched this topic
Carbon dioxide is returned to the atmosphere primarily by the
respiration of consumers. Explain: All living animals release CO2 back into the air
Which of these products is formed during the metabolic reactions of cellular respiration?
water Explain: 101 notes
________________ are reactants in the process of cell respiration.
Sugar and oxygen Explain: Found in our journals pretty clearly.
Using the image above, which statement does NOT accurately describe the relationship between photosynthesis and cellular respiration.
Water is required for both photosynthesis and cellular respiration. Explain: It is one of the main components for both
The model illustrates the relationship between photosynthesis and aerobic cellular respiration. Write balanced chemical equations showing the relationship between the two processes.
6H20 + 6CO2 + sunlight ⇒ 6O2 + C6H12O6 6O2 + C6H12O6 ⇒ 6CO2 + 6H2O + ATP Explain: Formulas that are found in our journals
Examine the model for two cellular organelles found in many eukaryotic cells. Which molecule(s) could be represented by the circle labeled Z that is produced as an output of the mitochondria and required by the chloroplast? Select ALL that apply.
Letter Z could be a water molecule because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be carbon dioxide because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be a glucose molecule because it is produced in photosynthesis and is a reactant of cellular respiration. Explain: Still need some help understanding this concept.
What is produced in photosynthesis that is required for aerobic respiration? Choose the TWO that apply.
O2 glucose Explain: These are the products of photosynthesis
Lilly and her lab partner, Alberto are investigating factors that influence the rate of photosynthesis. They know that any change to the reactants in photosynthesis could have an effect on the production of glucose and oxygen. In doing some research, the pair comes across the data shown above. They decide to brainstorm possible variables they could change in their experiment that could increase the rate of photosynthesis. Evaluate their list of possibilities. Based on the data and your knowledge of photosynthesis, what would you advise Lilly and Alberto to consider changing in their experiment if they wanted to increase the rate of photosynthesis? Choose ALL that apply.
Place the plants under blue light. Place the plants in a carbon dioxide-rich environment. Place the plant under a red light. Explain: Plants do good or bad depending on the type of light they receive and in this case, it was the color of the light that determined if the plants were going to do good or bad.
Water is one of the required reactants for photosynthesis. It provides electrons that are energized by sunlight and used to make energy carriers like ATP. Where do plants get the water they need for photosynthesis?
Plants take in water from the soil through their roots. Explain: The water fall on the ground and then the roots pick them up.
Which statement correctly describes the diagram?
The products of respiration can be used by plants for photosynthesis. Explain: What we release into the air the plants use as products to create O2 to make a cycle for us to breathe
