Answer:
a) Oxaloacetate.
b) Malate.
Explanation:
The malate-aspartate shuttle works in the mitochondria of the liver, kidney, and heart.
The cytosolic NADH reducing equivalents transfer to the cytosolic oxalacetate, producing malate, by the cytosolic malate dehydrogenase. This malate crosses the inner mitochondrial membrane throughout the malate-α-ketoglutarate transport system.
Inside the matrix, the reducing equivalents pass from the malate to the NAD⁺, forming NADH, by the action of the mitochondrial malate dehydrogenase. This formed NADH passes electrons directly to the respiratory chain.
The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
Answer: Your answer would be D. A neutral atom would become positively charged when they lose electrons because electrons are negatively charged. Removing some of these negative charges causes the atom to become more positively charged. Hope this has helped you :D
Answer:
The Kinetic Energy is approximately 3 times decreased
Explanation:
A baseball weighs 5.13 oz.
a)What is the kinetic energy, in joules, of this baseball when it is thrown by a major league pitcher at 95.o mi/h?
b) By what factor will the kinetic energy change if the speed of the baseball is decreased to 54.8 mi/h? Express your answer as an integer.
Kinetic Energy (KE)=0.5×mass×velocity ^ 2
Kinetic Energy (KE)=0.5×mass × velocity ^ 2
Joules = kg×m^2/s^2
1 mile = 1609.344 meters
1 hour = 3600 sec
1 Oz = 28.34952 g = 0.02834952 kg
a) KE=0.5×m×v^2
=0.5×(5.13 oz × 0.02834952 kg/1 ounce)×(95 miles/h × 1609.344 m/1 mile × 1 hr/3600 s)^2
=130.761 kg×m^2/s^2 = 130.761 Joules
b) KE=0.5×m×v^2
=0.5×(5.13 oz × 0.02834952 kg/1 ounce)×(54.8 miles/h × 1609.344 m/1 mile × 1 hr/3600 s)^2
=43.51028 kg×m^2/s^2 = 43.51028 Joules
= 130.761 / 43.51028 = 3.00528,
As such the Kinetic Energy is approximately 3 times decreased
