20) In order for high force cross bridges to form in contracting skeletal muscle, calcium must A) phosphorylate the troponin to

move the tropomyosin. B) bind to calmodulin to phosphorylate the myosin. C) phosphorylate the tropomyosin which moves it. D) bind to tropomyosin which moves the troponin. E) bind to troponin which moves the tropomyosin.

Answer:

E. bind to troponin which moves the tropomyosin

Explanation:

calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction

Drag the numbers to put the following steps in the correct order.
deff fn [24]

Answer:

- In glycolysis, glucose is split into two pyruvate and makes some ATP

- The Krebs cycle produces ATP, NADH and CO2

- NADH gives electrons to the ETC

- As electrons move down the ETC, a H+ gradient is made

- H+ pass through the ATP synthase to make ATP

Explanation:

This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).

- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.

- Kreb's cycle produces ATP, NADH and CO2.

- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).

- Electrons move down the ETC to produce a proton (H+) gradient

- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.

Describe neuroendocrine and metabolic aspects of endocrinology
geniusboy [140]

Answer:

Given the current environment in most developed countries, it is a challenge to maintain a good balance between calories consumed and calories burned, although maintenance of metabolic balance is key to good health. Therefore, understanding how metabolic regulation is achieved and how the dysregulation of metabolism affects health is an area of intense research. Most studies are focused on the hypothalamus, which is a brain area that acts as a key regulator of metabolism. Among the nuclei that comprise the hypothalamus, the arcuate nucleus is one of the major mediators in the regulation of food intake. The regulation of energy balance is also a key factor to ensure the maintenance of any species because of the dependence of reproduction on energy stores. Adequate levels of energy reserves are necessary for proper functioning of the hypothalamus-pituitary-gonadal axis. This review discusses valuable data presented in the 2015 edition of the International Workshop of Neuroendocrinology concerning the fundamental nature of the hormonal regulation of the hypothalamus and the impact on energy balance and reproduction.

Hope this is helpful, have a nice day! :)

Answer:

What does cellular respiration due?

<h2>Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.</h2>

Explanation:

<h2>What are the 7 steps of cellular respiration in order?</h2>

<h2>Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made.</h2>

...

<h2>Glycolysis. ... </h2><h2>Pyruvate oxidation. ... </h2><h2>Citric acid cycle. ... </h2><h2>Oxidative phosphorylation</h2>

<h2>Answer</h2>

<h2> Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.</h2>
