Noncyclic photophosphorylation

In humans this waste product is lactic acid, and it is produced when we do not get enough oxygen. As shown in Figure 8.6, a stack of thylakoids is called a granum, and the liquid-filled space surrounding the granum is called stroma or “bed” (not to be confused with stoma or “mouth,” an opening on the leaf epidermis). Carnivores at the top of the food chain eat herbivores that eat photoautotrophs. What about desserts and drinks?

In a (d) deep sea vent, chemoautotrophs, such as these (e) thermophilic bacteria, capture energy from inorganic compounds to produce organic compounds. 5.

A) photosynthesis. The breads, cereals, and pastas come largely from starchy grains, which are the seeds of photosynthesis-dependent plants.

Using a photosynthetic organism of your choice, choose only ONE of the three variables (temperature, wavelength,, or light intensity) and for this variable Although photosynthesis and cellular respiration evolved as independent processes—with photosynthesis creating an oxidizing atmosphere early in Earth’s history—today they are interdependent.

After that, you end up with 6 G3P.

Not all free-response questions on this page reflect the current exam, but the question types and the topics are similar, making them a valuable resource for students. Then by comparing this to our rates of photosynthesis it can be seen that photosynthesis has the fastest rate with dark blue and red light, with green light being absorbed the least.

In addition, several enzymes of the light-independent reactions are activated by light. Photosynthesis is a process where components of water and carbon dioxide are used to assemble carbohydrate molecules and where oxygen waste products are released into the atmosphere. Which of the following statements best represents the relationships between the light reactions and the Calvin cycle? These sugar molecules contain energy and the energized carbon that all living things need to survive. Cellular respiration requires glycolysis to produce NADP. If you are completing this FRQ as part of a classroom assignment, please check with your teacher on how to submit your answers. Virtually every spice and flavoring in the spice aisle was produced by a plant as a leaf, root, bark, flower, fruit, or stem.

noncyclic photophosphorylation occurs in the stroma

Free-Response Question and Scoring Archive. For plants, chloroplast-containing cells exist in the mesophyll. Only photosystem I is used during the cyclic process The, reaction begins when chlorophyll absorbs light photons and its electrons become elevated and, excited.

In this section, you will explore the following questions: As we learned in Chapter 7, all living organisms, from simple bacteria to complex plants and animals, require free energy to carry out cellular processes, such as growth and reproduction.

Sugar, 5. C4 plants fix the carbon into a 4 carbon sugar instead of a 3 carbon sugar, which minimizes photorespiration. Questions 3–8 are short free-response questions that require about 6 minutes each to answer. The main difference initially between aerobic and anaerobic metabolism is the inclusion of oxygen in aerobic and absence of it in anaerobic. During an investigation of a freshwater lake, an AP Biology student discovers a previously unknown microscopic organism.

Compare and contrast the processes of energy production in cellular respiration and photosynthesis in electron transport and chemiosmosis. covers, OpenStax CNX name, and OpenStax CNX logo are not subject to the Creative Commons license and may An overwhelming number of you guys wanted the solution set, so I'll just paraphrase into bullet points what the answer might be. In chlorophyll a, it absorbs the most energy with dark blue and red light. The reaction is catalyzed in plants by the enzyme polyphenol oxidase. This corresponds to the shape of the active site.

In the energy payoff phase, which follows immediately after. calvin cycle occurs half as often as the light dependent reaction A learning objective merges required content with one or more of the seven science practices.

glucose Then, one of these is taken out to make a sugar, and the other 5 are recycled and remade into RUBP. Skill, conceptual, and application questions combine to build authentic and lasting mastery of math concepts. Enzymes, 1.
