Answer:

The options

A ) It was thought that all ATP in the cell was synthesized from the glycolytic pathway in the cytosol and that mitochondria are dispensable.

B) It was thought that oxidative phosphorylation required a reactant with a high energy bond (~X) and it was just a matter of who could find it first.

C) The reaction A~X + Pi + ADP. A + X + ATP was thought to be the preferred pathway using both a membrane potential and Na+ gradient.

D) Since Peter Mitchell was a wealthy scholar who lived in a mansion with a built-in laboratory, it was assumed he was eccentric and wrong.

The CORRECT ANSWER IS B

B) It was thought that oxidative phosphorylation required a reactant with a high energy bond (~X) and it was just a matter of who could find it first.

Explanation:

Majority of the biochemists at that period were experimenting to evaluate for a high energy phosphorylated intermediate also known as ~X-P and they believed it is the answer to the question or experiment.

Peter Mitchell's hypothesis was considered heretical because it was independent on ~X-P. His model was considered unusual and a new model plus he had his own private laboratory... a factor wasn't common too at that period.

It was called "Ox Phos War due to the disagreement "war" as biochemists had to chose sides.

Label each organism in the food web as a producer, consumer, or decomposer. Hope u can help.

ira [324]

Hi, The center image is a decomposer because it decomposes the dead organisms. The grass is a producer since it produces its own energy through photosynthesis. The rest are consumers because they consume other organisms to get energy. Hope that helped!

At the site of the rough endoplasmic reticulum, proteins that are destined for secretion are manufactured. Insulin is a protein-

Eva8 [605]

Answer:

The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.

Explanation:

In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.

Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.

In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).

Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

A boy threw a small bundle toward his girlfriend on a balcony 10. meters above him. The bundle stopped rising in 1.5 seconds. Ho

Alisiya [41]

Hi!

We know that the boy must have thrown the bundle with some initial velocity 'v', and that the bundle stops after 1.5 seconds at a height 's' with a final velocity 'u' -which would be 0.

Our known values thus are:

Time (t) = 1.5 s

Final velocity (u) = 0 m/s

Gravitational acceleration (g) = -9.8 m/s^(2)

<em>Note: that the acceleration is negative as it is opposing the direction of motion (acting down on the object, causing deceleration)</em>

We will be using <em>equations of motion for an accelerating object</em> to solve first for initial velocity, in order to find the distance.

<h3>Initial Velocity using <u>v = u + at</u></h3>

Rearranging the equation, and using the value 'g' as our acceleration, we get,<em> u = v - at</em>

u = 0 - (-9.8)(1.5) = 14.7m/s

<h3>Distance Travelled using <u>v^2 = u^2 + 2as</u></h3>

Rearranging the equation, we get, <em>s= v^(2) - u^(2) / 2a</em>

s = 0^(2) - 14^(2) / 2(-9.8)

<em>Note: the negative sign is not a part of the initial velocity, but a part of the equation </em>

s = - 216.09 / -19.6 = 11.025 m

The distance traveled by the bundle is hence, ~ 11 meters, which is high enough for the girl to catch.

Hope this helps!

The most accurate explanation of how and why the gm stock went up is because not only can it drive you places, it can cure diseases such as cancer and heart disease.
