serg [7]

Answer:

I think they're neither perpendicular nor parallel

Explanation:

Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)

Not perpendicular since the product of their slopes isn't equal to - 1.

=> (3/5)(-8/3)= - 8/5 and not - 1

(plz make sure you typed the equations correctly.)

Hope this helps..

Sergeu [11.5K]
The two bacteria are considered to be anaerobic endospore-formers that deliver neurotoxins. Disease comes about when the endospores are brought profound into the tissues. The two neurotoxins meddle with engine control. Botulism poison, delivered by C. botulinum, ties the cytoplasmic films of engine neurons at the neurotransmitter and keeps the arrival of acetylcholine neurotransmitter and, subsequently, forestalls motioning to muscle cells. At the point when muscle cells don't get signals from engine neurons, they stay loose, bringing about a flabby loss of motion. The absence of engine control delivers a not insignificant rundown of side effects, the most genuine of which is a respiratory disappointment, on the grounds that respiratory muscles can be influenced by botulism poison.

When NADH is the electron donor to the respiratory chain, 2.5 ATP are formed, but when FADH2 is the electron donor, only 1.5 ATP
Fofino [41]

Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.

Explanation:

Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.

NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.

While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.

So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.

Electrons are removed from their carrier molecules as the molecules will lose energy bit by bit

Protons are moved across a membrane

Oxygen is not a waste product since it is very useful, water is the waste product

Carbon Dioxide is released as it is another waste product
