QuestionAnswer
What systems of the body are important for thee gas exchange necessary for cellular respiration? Respiratory System
... D&E
What is the overall equation for the cellular respiration of glucose? C6 H12 O6+602--> 6CO2+6H2O+energy
What are the steps for aerobic respiration? Glycolysis, Pyruvate link reaction, citric acid cycle, electron transport chain
How do cells capture the energy released by cellular respiration? They produce ATP
Which of the metabolic pathways is common in aerobic and anaerobic respiration? Glycolysis
What is a result of glycolysis? conversion of glucose to two three carbon compounds
The enzymes of the citric acid cycle are located in the... mitochondria matrix and inner mitochondria membrane
The mitochondria cristae are an adaptation that .. increases the surface area for more copies of the electron transport chain and an ATP synthase complex
In the electron transport chain, the final electron acceptor is.. oxygen
Insects exposed to rotenone will die because... they will no longer be able to produce adequate amounts of ATP.
What systems of body are important for delivering sugars necessary for cellular respiration? digestive system
Which of the following processes produces the most ATP per molecule of glucose oxidized? aerobic respiration
If OXYGEN... is not present the pathway labeled C in the figure usually will not occur
Based on figure 9.... 2 ATP molecules per glucose molecule are generated through fermentation
The pathway labeled B is called ALCOHOLIC FERMENTATION
The only pathway labeled C=requires oxygen
Some friends are fermenting wine but low sugar no alc, the explanation: mixture needs less oxygen bc yeast only produce alcohol in the absence of oxygen
A drug will make holes in mitochondria, it will be harmful bc it will inhibit the citric acid cycle and electron transport chain
Which of the following statements abt oxygen is false? oxygen is required for all methods of respiration
The end products of the citric acid DONT include pyruvate
NADH pills purchased over counter. What is the hypothesis abt how these epills benefit CFS patient? they would increase the number of electrons provided to electron transport chain
Marathon runner contains slow twitch muscle cells. Which of the following statements abt these fibers are true? Slow-twitch fibers have lots of mitochondria to make ATP aerobically
During a gas exchange, body cells release CO2 and take up O2
The conversion of CO2 and H2O in organic compounds using energy from light is called photosynthesis
What is produced during the light reactions of photosynthesis? ATP, NADPH, O2
Which of the following molecules are products of photosynthesis? glucose and O2
The energy that excites the photosystems is supplied by photons of light
In photosynthesis, the chemiosmotic production of ATP requires oxygen
Mitochondria transfers ___ energy from ____ to ATP, chloroplasts transform___ energy into chem energy of ATP> chemical;food;light
photosynthetic organisms derive their carbon from carbon dioxide
ATP and NADPH power sugar synthesis during the Calvin cycle
the ultimate source of all the food we eat and oxygen we breathe is photosynthesis
Plant cells... have mitochondria and chloroplasts
Global warming due to the greenhouse effect may be moderated by photosynthesis, which removes CO2 from the atmosphere
what wavelengths of light would you expect red algae to use? blue
Which is the best explanation on how this mimics photosynthesis? both this proposed process and photosynthesis split water into hydrogen and oxygen
CO2 enters and O2 escapes from leaf via stomata
The light reactions occur in the___while the eclavin cycle occurs in the ____ thylakoid membrane;stroma
which of the following statements comparing photosynthesis and cellular respirations is false? ATP is not produced during photosynthesis; it is produced only during cellular respiration
in which of the products of photosynthesis will the radioactive H and O show up? H in glucose; O in O2
Why are most plants green? chlorophyll a reflects green light
what are the advantage of plants having multiple pigments in their photosynthesis? absorb more wavelengths of light
Chlorophyll is located in which are found in and concentrated in thylakoids chloroplasts mesophyll tissue
What is name to given to organisms that can make their own food? autotrophs
what is the main adaptive advantage of C4 and CAM photosynthesis strategies over C3 strategy? they help plant synthesize glucose efficiently under dry cpnditions
What are two physical adaptations plants have to minimize water loss? guard cells surround stomata, waxy cuticle secreted by epirdemis
Describe 2 ways bodily anatomy of plants or animals is adapted to increase SA for energy collection: -the broad flat leaves on plants maximize sunlight absorption for photosynthesis -the branching out of lungs in respiratory system branch out to take up as much space as they can for gas exchange quicker
Describe 2 ways plant or animal cells are adapted to increase SA -plants have root hair cells with long finger like extensions to maximize water absorption from the soil -animals have folded intestinal microvilli that increase absorption as well
2 similarities of photosynthesis and cellular respiration: -both processes involve production and using ATP to power cellular activities -both rely on electron transport chains and chemiosmosis and each others outpouts
2 differences of photosynthesis and cellular respiration: -phoptosythesis uses light to synthesize food, while cellular respiration breaks down food to release enrgy -phoptosythesis needs Co2 and H2O while cellular respiration needs glucose and O2
