What is the ingroup in a cladogram?
V125BC [204]

Answer:

•Ingroup in biology is a group of taxa that is considered in determining evolutionary relationships. The taxa in an ingroup are closely related. In fact, they are sister groups, and they share a common ancestor. Therefore, taxa in an ingroup are descendants that split from the same node in the cladogram.

Most of the atp supplies for a skeletal muscle undergoing one hour of sustained exercise come from _____.
ioda

The question is incomplete as it does not have the options which are:

A) creatine phosphate.

B) glycolysis.

C) substrate phosphorylation.

D) oxidative phosphorylation.

E) de novo synthesis.

Answer:

D) oxidative phosphorylation.

Explanation:

The ATP is the energy molecule which provides energy to every metabolic process in the organism.

The ATP in humans is produced by a process called cellular respiration where the last phase of the process called electron transport chain produces the highest amount of protein. The electron transport chain is also known as the oxidative phosphorylation as the oxygen is gained and electrons are lost during the phase.

Thus, D) oxidative phosphorylation is correct.

A proton gradient is an important part of both photosynthesis and cellular respiration.
Dennis_Churaev [7]

A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.

<h3>What is the proton gradient?</h3>

The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.

The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.

The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.
