Chloroplast & Mitochondria
How do cells capture the energy released by cellular respiration?
ATP
Cellular respiration equation:
C6H12O6+6O2——->6CO2+6H2O+ATP
The processes of photosynthesis and cellular respiration are complementary during these energy conversions some energy is?
Saved in the chemical bonds of H20, CO2, & O2
Following are products of cellular respiration?
Carbon Dioxide & Water & ATP
If your bowl of cereal contains 200 Cal how many regular calories does it have?
kCal: 200,000
During cellular respiration, energy and glucose?
Is carried by electrons
In biological systems an important enzyme is?
Whatever ends in -ase
A drug is tested in a lab and is found to make holes in both mitochondrial membranes (inner and outer), scientists suspect it will be harmful to human cells because it will inhibit?
(Holes in mitochondrial membrane) will affect both the citric acid cycle and phosphorylation.
Which of the following metabolic pathways is common to both aerobic and anaerobic respiration?
Glycolysis
As a result of glycolysis, there is a net gain of how many ATP?
2 ATP
How many molecules of NADH are produced during one round of glyocolysis?
2 NADH
Which of the following is a result of glycolysis (What comes out of glycolysis)?
The conversion of glucose to 2 three-carbon compounds.
Which of the following corresponds to pyruvate?
Pyruvate forms at the end of glycolysis (Pyruvate is the 2 three-carbon molecules)
The enzymes of the citric acid cycle are located where?
the outer mitochondrial membrane
The end products of the citric acid cycle include all of the following EXCEPT:
Pyruvate
Byproducts (end result) of cellular respiration include:
Carbon dioxide & Water
Which of the following statements about the energy yield aerobic (needing oxygen) respiration is FALSE?
Oxidative phosphorylation results from one glucose molecule and yields 12 ATP molecules. (its 32 ATP)
Which of the following produces the most ATP per glucose molecule?
Aerobic respiration
Some friends try to make wine: they add yeast to a sweet grape juice mixture, after a few days they see the sugar levels have dropped but there is still no alcohol in the mixture. What is the most likely explanation?
The mixture needs less oxygen because yeast only produces alcohol in the absence of alcohol.
In yeast cells, which is false?
alcohol is produced during glycolysis
(NOT LATIC ACID)
To obtain energy from starch and glycogen the body must begin by?
Hydrolyze both starch and glycogen to glucose
When a cell uses fatty acids for aerobic respiration it first hydrolyzes fats into what 2 products?
Glycerol and fatty acids
What is the process called that converts CO2 and water to an organic compound using energy from light?
Photosynthesis
What is the name given to organisms that can make their own food?
Autotroph (Auto: Self, Troph: Food, makes its own food)
Which of the following is an example of a photoautotroph?
Grass on the front lawn (has to be plant to make its own food)
What do you call an autotroph that uses light for energy?
Photoautotroph
CO2 Enters and Oxygen Escapes from a leaf via what structure?
The STOMA
In the cholorplast, sugars are made in a component filled with thick fluid called?
STROMA
What is a stack of thylakoids called?
A Grana
Where is chlorophyll found in a plant cell?
Thylakoid membrane
Oxygen released into the air as a product of photosynthesis comes from?
Water
