The energy used to pump hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space is derived from:________

a. ATP hydrolysis
b. reactions in the electron transport chain
c. decreasing the pH in the mitochondrial matrix
d. splitting water to form oxygen and protons

Answers

Answer 1

Answer:

b. reactions in the electron transport chain

Explanation:

Oxidative phosphorylation, which is the process described in this question, is the third stage of cellular respiration which occurs in the MITOCHONDRION of eukaryotic cells. In this stage of oxidative phosphorylation, which encompasses electron transport chain (ETC) and chemiosmosis, ATP is synthesized.

The ATP is synthesized when protons (H+) move from the mitochondrial matrix into the intermembrane space, forming, a proton pump. The series of electron transfers (reactions) that occur in the complexes of the ETC provides the ENERGY to pump the protons/hydrogen ions out of the matrix, which creates the electrochemical gradient required for ATP synthesis with the help of ATP synthase.

itself up 2 m. What is the gravitational field strength on the planet?

Answers

Answer:

the gravitational field strength is 8.5 N/kg .

Explanation:

PE = mgh

where,

PE is Potential Energy

m is the mass

g (a) is the acceleration

h is the height

Substitute the value we get

→ 850 = 50×a × 2

→ 850 = 100×a

→ a = 850/100

→ a = 8.5m/s²

Acceleration is 8.5m/s².

Now, Calculating the Gravitational Field Strength

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?

Answers

Answer:

The correct approach is "Negative and Positive".

Explanation:

Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.

For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

Please answer this is super easy 6th grade science! Thanks!

Answers

Answer:

The answer should be A. lithosphere.

Explanation:

Firstly, let's look at the options:

C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.

B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.

Therefore, finally, we have A as the answer.

(As a sidenote, the "lithosphere" means the Earth's crust.)

Hope this helped!

The lithosphere contains the tectonic plates, so that’s the answer.

Which scientific discipline is correctly matched to a contribution to society?

Answers

The options are;

A) biology; theory of relativity

B) geology; theory of continental drift

C) ecology; discovering new elements

D) astronomy; developing quantum mechanics

Answer:

B) geology; theory of continental drift

Explanation:

Looking at the options;

-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.

- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.

- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.

-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.

Therefore correct answer is option B

What prevents acetylcholine from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual

Answers

Answer:

Botulinum toxin

Explanation:

Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.

This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.

Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.

Which of the following statements BEST defines vestigial structures? :
-Structures that are different in different organisms
-Structures that are still present but currently serve little to no purpose
-Structures that are the same in different organisms
-Structures that are different between the infant and adult forms of an organism

Answers

Answer:

Structures that are still present but currently serve little to no purpose

Explanation:

Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.

Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the caudal vertebrae found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.

Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.
