Slide 4 / 51 1 The wavelength and frequency of a photon determines the energy level of that photon. The wavelength of a photon is directly proportional to velocity and indirectly proportional to frequency as shown in the following equation: λ = v/f. What Answer is the frequency, in seconds, of a photon with a wavelength of 525 nm and a velocity of 3.00 x 108 m/s? Slide 4 (Answer) / 51 1 The wavelength and frequency of a photon determines the energy level of that photon. The wavelength of a photon is directly proportional to velocity and indirectly proportional to frequency as shown in the following equation: λ = v/f. What Answer is the frequency, in seconds, of a photon with a 5.71 x 10 14 s wavelength of 525 nm and a velocity of 3.00 x 108 m/s?

FADH2 donates electrons at a different location on the chain than NADH and, therefore, results in the creation of less ATP than Answer NADH. In fact, every FADH2 molecule creates 1.5 ATP while every NADH molecule creates 2.5 ATP. In a catabolic process that results in 11 NADH and 3 FADH2, how many ATP can be created from the electron transport chain?

FADH2 donates electrons at a different location on the chain than NADH and, therefore, results in the creation of less ATP than Answer NADH. In fact, every FADH2 molecule creates 1.5 32 ATP ATP while every NADH molecule creates 2.5 ATP. In a catabolic process that results in 11 NADH and 3 FADH2, how many ATP can be created from the electron transport chain?

A byproduct of the process is heat, which endotherms use to maintain a constant body temperature. The efficiency of respiration is a calculation that Answer determines what percentage of glucose is actually converted to ATP, as opposed to being released as heat. Efficiency is expressed as a percentage. Use the following information to calculate the percentage of the oxidation of glucose that is stored in ATP. The oxidation of one mole of glucose under standard conditions releases 686 kcal/mol. The phosphorylation of ADP to ATP stores 7.3 kcal/mol and, under best conditions, cellular respiration creates 32 ATP. Slide 6 (Answer) / 51 3 During the process of cellular respiration, glucose is broken down to release energy. A byproduct of the process is heat, which endotherms use to maintain a constant body temperature. The efficiency of respiration is a calculation that Answer determines what percentage of glucose is actually 34% converted to ATP, as opposed to being released as heat.
