The diagram shows the structure of an ATP molecule.

Assume that endogenous acid production is 40 meq during a 12-hr period. A urine sample collected during this time contains 30 mm

MrMuchimi

Answer:

Thus, the Quantity of $HCo_{3}^{-}$ Present in urine sample in 24 hours is 35mmol

Explanation:

Acid Production in 12 hours = 40 meq

For, 24 hours = 40 meq × 2

Acid Production in 24 hours = 80 meq

Urine sample for $NH4^{+}$ = 30mmol

$HCo_{3}^{-}$ Present in Urine Sample in 24 hours

= Acid Production - Urine sample for $NH4^{+}$ - Titratable Acid

= 80 - 30 - 15

= 50 - 15

= 35mmol

$HCo_{3}^{-}$ Present in urine sample in 24 hours is 35mmol

Which of the following is an unsual nucleoside that is found in tRNA but not mRNA?

gizmo_the_mogwai [7]

Answer:

Inosine

Explanation:

Inosine the unusual nucleoside which is found in tRNA but not in mRNA.
Inosine is derived from the nucleoside adenosine, adenosine is present in mRNA, however in case of tRNA, there is deamination of adenosine and thus, inosine is formed.
The enzyme that is responsible for carrying out this reaction is called as tRNA A:34 deaminases, here the position 34 indicates that the deamination takes place at position 34 of the tRNA.
The formation of inosine is essential for the wobble base pairing to take place.
The formation of inosine takes place when the hypoxanthine attaches to a ribose ring with the help of the beta glycosidic bond.

Which specific process in the light dependent reactions produce oxygen and hydrogen ions? A- The formation of NADPH

garri49 [273]

Light-dependent reactions involve a series of events that involve electrons moving along the transporter chain. Water provides the electrons, releasing oxygen and hydrogen ions. C) The splitting of water

<h3>What are the light-dependent reactions?</h3>

Photosynthesis involves two stages: light-dependent and light-independent reactions.

Light-dependent reactions occur in the thylakoids of chloroplasts. They Involve the noncyclic pathway which is a flow of electrons along a chain located in the thylakoid membrane.

Photosynthetic pigments are in charge of light absorption. When sunlight reaches the pigments, electrons provided by water get excited and move along the electron transport chain.

During these reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.

The steps of light-dependent reactions are the followings,

1) Luminous energy is trapped by chlorophyll in Photosystem II.

2) When the pigment molecules absorb light, electrons provided by water molecules get to a higher energy level.

3) The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.

4) When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.

5) The absorbed luminous energy moves the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.

6) When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.

7) When the water molecule breaks down, it releases oxygen and hydrogen ions, which remain in the thylakoid lumen. From there hydrogen ions are pumped to the stroma by the ATP synthase.

8) The released energy is used to produce ATP molecules.

9) Hydrogen ions go back from the stroma to the thylakoid compartment.

According to this information, the correct option is C- The splitting of water.

Water breaks down and releases oxygen, hydrogen ions, and provide electrons to the chain.
