What Process Occurs In Box A

Last Updated on October 1, 2022 by amin


What processes use electron transport?

The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis β-oxidation and other catabolic processes are oxidized thus releasing energy in the form of ATP. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation. See also why did edgar allan poe write the raven

Where does the citric acid cycle occur in eukaryotic cells quizlet?

The Citric acid cycle occurs in the mitochondria.

Which one of these reaction occurs during photosynthesis?

Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis.

What are the 3 stages of cellular respiration list them in the order they occur where in the cell does each of these stages occur What is the main goal of each stage?

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm the Kreb’s Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

How is energy transferred by electrons?

Conduction in metals The electrons in a piece of metal can leave their atoms and move about in the metal as free electrons. … This kinetic energy is transferred from hot parts of the metal to cooler parts by the free electrons. These move through the structure of the metal colliding with ions as they go.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. … Photosynthesis requires sunlight chlorophyll water and carbon dioxide gas. Chlorophyll is a substance in all green plants especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

What is the main transformation that occurs during glycolysis?

During glycolysis glucose is broken down into two molecules of pyruvate. What is the main transformation during glycolysis? Glycolysis produces pyruvate ATP and NADPH by oxidizing glucose. During cellular respiration glucose combines with oxygen to form carbon dioxide water and ATP.

What are the 3 phases of the cellular respiration process?

The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1) the Krebs cycle also called the citric acid cycle (stage 2) and electron transport (stage 3).

Where do the electrons come from in glycolysis?

As in aerobic respiration Glycolysis also delivers high-energy electrons taken from glucose to electron carriers. In order for glycolysis to occur that is in order to split a molecule of glucose into 2 molecules of pyruvate some electrons must be removed from glucose.

What occurs during absorptive state?

The absorptive state or the fed state occurs after a meal when your body is digesting the food and absorbing the nutrients (catabolism exceeds anabolism). Digestion begins the moment you put food into your mouth as the food is broken down into its constituent parts to be absorbed through the intestine.

Where do the reactions of the citric acid cycle occur in eukaryotic cells?

Explanation: The citric acid cycle also known as the Kreb’s cycle occurs within the mitochondria of eukaryotic cells. In prokaryotic cells it occurs in the cytosol.

Which electron carriers function in the citric acid cycle?

The electron carriers that function in the citric acid cycle are FADH2 and NADH.

Where does etc occur in mitochondria?

Explanation: The mitochondrion has an outer membrane and an inner membrane with folds (cisternae). The electron transport chain is a series of transmembrane proteins found in the inner membrane.

Which chemical process generates the ATP produced in the citric acid cycle?

Oxidative phosphorylation the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP producing ATP.

How is energy released in a cell?

Cells can release energy in two basic processes: cellular respiration and fermentation. … In fact most of the energy used by the cells in your body is provided by cellular respiration. Just as photosynthesis occurs in organelles called chloroplasts cellular respiration takes place in organelles called mitochondria.

Which chemical process generates the ATP produced in glycolysis quizlet?

Which chemical process generates the ATP produced in glycolysis? Substrate-level phosphorylation.

How is energy released in NAD+?

This is where NAD+ comes in. During the process of glycolysis where the sugar glucose is broken down energy is released in the form of electrons. … In this reaction NAD+ accepts electrons and hydrogen thus two molecules of NADH are formed for every one molecule of glucose.

Which of the following processes does not occur during the absorptive state?

fatty acids. Which of the following does NOT occur during the absorptive state? The process of storing glucose as glycogen is known as: gluconeogenesis.

What are the 3 stages of cellular respiration?

Summary: the three stages of Aerobic Respiration Carbohydrates are broken down using all three stages of respiration (glycolysis citric acid cycle and the electron transport chain).See also what is demographic factors

Which of these enters the citric acid cycle ?’?

Two electrons two hydrogen ions and an oxygen atom combine to form water. Which of these enters the citric acid cycle (also called the Krebs cycle)? Acetyl CoA is a reactant in the citric acid cycle (also called the Krebs cycle).

What is the process of storing glucose called?

Glycogenesis is the process of glycogen synthesis in which glucose molecules are added to chains of glycogen for storage. This process is activated during rest periods following the Cori cycle in the liver and also activated by insulin in response to high glucose levels.

What are the 4 stages of cellular respiration?

The stages of cellular respiration include glycolysis pyruvate oxidation the citric acid or Krebs cycle and oxidative phosphorylation.

How do electrons get to the electron transport chain?

All of the electrons that enter the transport chain come from NADH and FADH 2​start subscript 2 end subscript molecules produced during earlier stages of cellular respiration: glycolysis pyruvate oxidation and the citric acid cycle.

What are the 7 steps of photosynthesis?

Terms in this set (7)

  • Step 1-Light Dependent. CO2 and H2O enter the leaf.
  • Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid splitting the H2O into O2.
  • Step 3- Light Dependent. The electrons move down to enzymes.
  • Step 4-Light Dependent. …
  • Step 5-Light independent. …
  • Step 6-Light independent. …
  • calvin cycle.

Which of the following does not occur in the mitochondria?

Glycolysis is the only metabolic process of the choices listed that does not occur in the mitochondrion it occurs in the cytoplasm. Citric acid cycle and Krebs cycle refer to the same process which occurs in the mitochondrion.

Where does the oxidative phosphorylation occur?

the mitochondriaOxidative phosphorylation occurs in the mitochondria of all animal and plant tissues and is a coupled process between the oxidation of substrates and production of ATP. As the Kreb’s cycle runs hydrogen ions (or electrons) are carried by the two carrier molecules NAD or FAD to the electron transport pumps.

What process occurs in Box A Chapter 6?

What process occurs in Box A? The citric acid cycle transfers electrons to NADH and FADH2. … Oxygen is the final electron acceptor of cellular respiration.

What process occurs at B?

Name the process occurring at B and explain what results from it. It is Sea-floor spreading and they are making a mid ocean ridge. What happens to old oceanic crust as new molten material rises from the mantle? … The arrows on the diagram show the ocean floor spreading from the ridge.

Where does electron transport chain occur?

The electron transport chain is a series of four protein complexes that couple redox reactions creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Which process occurs within the mitochondria?

Mitochondria using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
