2. There are two types of plants, C3 and C4. C3 plants use the Calvin Cycle to generate sugar. C4 plants use phosphoenol pyruvate to make malate and oxaloacetate which will eventually be used to make sugar. Both types of plants have stomatas (openings on leaves that can be opened and closed) for CO2 entry. In addition, water is also lost through the stomata. C3 plants are only able to synthesize sugar at relatively high CO2 levels because photosynthesis will stop when CO2 production from the mitochondria equals the use of CO2 in the chloroplasts. C4 plants are able to continue photosynthesis even at low CO2 levels. (1) Why are C4 plants able to survive in hot, dry conditions when C3 plants are not? (2) Plants can develop cancer but it is usually from an infection not from the ionizing rays of the sun. What part of the photosynthesis pathway do you think protects the plant form sun damage?

Afterdisrupting mitochondria with ultrasound it is possible to isolatefunctional submitochondrial particles, which consist of brokencristae that have resealed inside-out into small closed vesicles.In these vesicles the components that originally faced the matrixare now exposed to the surrounding medium. You begin you experimentby isolating submitochondrial particles under anaerobic condition.Then you add a small, defined amount of oxygen to these particles,and immediately start monitoring oxygen level and pH in the mediumoutside the particles. For the condition listed below, state: 1)whether oxygen level will rise, fall, or remain constant, and 2)whether pH in the medium will rise, fall, or remainconstant.

Condion A:no inhitors were added to the particles (normalcondition)
ConditionB: uncoupling agent was added to the particles.
ConditionC: inhibitor of ATP synthase was added to theparticles
ConditionD: inhibitor of electron transport chain was added to theparticles.

Explainyour answers.

I got thisquestion wrong on my exam, The instructor did not explain to us,nor did he tell us the answer to this problem. Can someone pleaseanswer the question for me. Answering whether oxygen level willrise, fall, remain constant for the 4 condition. Also whether thepH in the medium will rise, fall or remain constant for the 4condition. And please explain your answer. Thankyou.

Please respond to the following questions throughout the week.

Provide an example of a food chain in the area where you live.

Humans are parts of food chains and food webs, too. Where on a food web would you typically find humans (near the bottom with the producers, at the top with carnivores, or somewhere in between)? Explain.

What are some advantages of being part of a food web rather than a food chain?

For Questions 4รขย€ย“6, use the following food web for Lake Michigan:

Lake Michigan Food Web. (2016). Retrieved fromhttps://www.glerl.noaa.gov//pubs/brochures/foodweb/LMfoodweb.pdf

To see this PDF, you will need to download the free Adobe Reader.

In the Lake Michigan food web, is it possible to identify the most important producer? Why or why not?

Provide at least two types of impacts that humans could have on this food web.

Read the description of the sea lamprey on page 2 of the food web. This species is described as non-native. They reached the lake through canals and locks built in the 1800s.

What challenges could occur within a food web when a new predator like this is introduced into an ecosystem?

Do you think steps should be taken to eradicate this species from the food web? Explain why or why not? If so, what steps can be implemented?
