How the proton H gradient is used to make ATP

Chemistry
1 answer:
sladkih [1.3K]3 years ago
4 0

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl
NikAS [45]

Answer:

Structures are given below.

Explanation:

  • Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
  • H atoms adjacent to Br will be eliminated.
  • 2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
  • Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
  • Structure of alkenes are given below.

Extension: Cedric has been in the hospital for 15 weeks, how many minutes is that? Use
almond37 [142]

Answer:

151200 minutes.

Explanation:

From the question given above, the following data were obtained:

Time (in week) = 15 weeks

Time (in min) =?

Next, we shall convert 15 weeks to days. This can be obtained as follow:

1 week = 7 days

Therefore,

15 weeks = 15 weeks × 7 days / 1 week

15 weeks = 105 days

Next, we shall convert 105 days to hours. This can be obtained as follow:

1 day = 24 h

Therefore,

105 days = 105 days × 24 h / 1 day

105 days = 2520 h

Finally, we shall convert 2520 h to mins. This can be obtained as follow:

1 h = 60 mins

Therefore,

2520 h = 2520 h × 60 mins / 1 h

2520 h = 151200 mins

Thus, 15 weeks is equivalent to 151200 minutes.

Which is the pathway of light as it travels through the eye?
KATRIN_1 [288]

Cornea - lens - retina

Explanation:

The pathway of light into the eyes goes from the cornea through the lens where it gets focus on the retina and optic nerves picks up the signal where the brain interprets the image. The eye is the organ of sight.

  • When light rays from objects hits the human eye, it goes through the cornea first. In the cornea the image begins to form and using the pupil located in it the amount of light that enters is regulated.
  • From the cornea, light goes into the lens. The lens allows for the rays to focus on the retina.
  • The retina receives the rays and the image forms .
