what is the net yield of atp when palmitate (c16) is completely oxidized via the β-oxidation pathway? express answer as whole nu
wariber [46]

When palmitate (C16) completely oxidized, net yield is 129 ATP.

There are 7 β-oxidation cycles for palmitate to completely oxidazed.

One β-oxidation (beta-oxidation) cycle produces 1 NADH, 1 FADH2, and 1 acetyl CoA (sea the picture below).

For 7 cycles: 7 NADH, 7 FADH2,  and 8 acetyl CoA.

NADH and FADH2 enter Electron Transport System (ETS) cycle to generate 3ATP and 2ATP respectively.

Acetyl CoA enter into tricarboxylic acid cycle (TCA) and each CoA gives 12 ATP.

7 NADH = 7 x 3 = 21 ATP

7 FADH2 = 7 x 2 = 14 ATP

8 acetyl-CoA = 8 x 12 = 96 ATP

Net yield of ATP = 21 ATP + 14 ATP + 96 ATP - 2 ATP (used during conversion of palmitic acid into palmitoyl CoA)

Net yield of ATP = 129 ATP

Which of the following are examples of plasma?
artcher [175]
The answers are "t<span>ails of comets, the ionosphere, and a neon sign." or options A, D, and E. Tails of comments are mainly made of plasma. Ice cubes are examples of a solid. A gas fire key word gas is example of a gas. The ionosphere is also mainly made of plasma. A neon sign uses plasma in order to work. A flashlight uses a light bulb which isn't a example of plasma therefore  thats a no.

Explanation:

density=mass/volume

convert mass in kg to g

1kg=1000g

5kg=5000g

therefore, density=5000g/50cm^3

=100g/cm^3
