Where is ATP produced in photosynthesis?

Where is ATP produced in photosynthesis?

thylakoid membrane

Where in the cell is the enzyme that produces the most ATP?

mitochondria

What accounts for the different number of ATP molecules that are formed through cellular respiration?

What accounts for the different number of ATP molecules that are formed through cellular respiration? The electron transport chain differs in composition between species, so different organisms will make different amounts of ATP using their electron transport chains

What is the relationship between the ETC and oxygen?

What is the relationship between the ETC and oxygen? The relationship between the two is that ETC allows cytochrome to pass into it’s final acceptor oxygen.

What is the difference between cellular respiration and photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How does pH affect ATP synthesis?

Low pH increases the concentration of base causing mitochondria to pump out H+ to the inter membrane space leading to ATP production. The high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase.

What is the optimal pH for ATP production?

between 7.25 and 7.75

Does H+ lower pH?

The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

How does temperature affect ATP synthesis?

If, at 4°C, ATP synthases generally become inhibited, then to minimize the restriction imposed, it could be hypothesized that ATP synthase activity and/or abundance is increased. Thus, when plants are returned to higher, more moderate temperatures, ATP synthases or hydrolysis is enhanced

Why does rate of respiration increase with temperature?

The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow

Do mammals respire more in colder temperatures?

In most animals, a rise of 10 degrees in body temperature causes a 2- to 3-fold increase in the rate of oxygen consumption. However, this is not always the case; especially for birds and small mammals, the most commonly used experimental subjects for such studies.

What is the net number of ATP produced under ideal conditions?

38

How many molecules of ATP can be produced from one molecule of glucose when oxygen is present and oxygen is absent?

two molecules

How does etc produce ATP?

The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.

Why does the electron transport chain produce the most ATP?

During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP. The most vital part of this process is the electron transport chain, which produces more ATP than any other part of cellular respiration.

What are the main components of electron transport chain?

The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3)

What is the end product of respiration?

End products of respiration are carbon dioxide, water and energy in the form of ATP
