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.

When the term biceps, triceps, or quadriceps forms part of a muscle's name, what does it tell you about the muscle? the muscle h
tekilochka [14]

Answer:

The muscle has two, three, or four origins, respectively.

Explanation

  • A muscle is an organ composed of muscle tissue that contract to facilitate a particular movement
  • biceps,triceps and quadriceps  are types of skeletal muscles since they use bones as levers
  • <em><u>They differ in that; the biceps have two origins, triceps have three origins and quadriceps have four origin.</u></em>
  • <em><u>Bicep is a two headed muscle thus said to have two origins ,triceps have three muscle heads and therefore have three separate origin attachment point while quadriceps are made of four muscles heads hence have four origins. </u></em>

What subatomic particle is transferred to the electron transport system from the krebs cycle?
mario62 [17]
<span>Electrons are transferred via Hydrogen atoms bound to NAD (nicotinamide adenine dinucleotide). Essentially, the krebs cycle harvests electrons (Hydrogen atoms) from pyruvates in the inter-membrane space via NADH and these feed into the electron transport chain to power ATP synthase to generate ATP.</span>

Explain the following statement: "Selection occurs within
True [87]

Answer: Selection occurs within generations; evolution occurs between generations. All four of Darwin's postulates are true for the medium ground finch population on Daphne Major. Darwin's theory therefore predicts a change in the composition of the population from one generation to the next. In biology, evolution is the change in the inherited traits of a population from generation to generation. ... Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare.
