Using the table below, what is the total net gain of ATP molecules per glucose molecules?

svlad2 [7]

Explanation:

D. 38 ATP

During respiration, the breakdown of glucose undergoes several steps in order to produce ATP, namely in glycolysis, the Kreb's cycle and oxidative phosphorylation.

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Net ATP: 2+ 2+ 34= 38 ATP

(Q002) Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipeda

Artemon [7]

Answer:

One good example of a living non-primate that is also a biped is a Kangaroo. With so much power in their legs and vertebral column like humans, kangaroos are biped, but they leap rather than walk. Their legs are usually bigger than their arms, which enables them to push their whole body off the ground.

However, kangaroos are not just bipedal or quadrupedal but they are both. They also hop bipedally like rodents and many birds, with some displaying skipping gaiety. In addition, chimpanzees, gorillas, gibbons, macaques, capuchins, birds, many lizards, and (at their highest speeds) cockroaches run bipedally.

Explanation:

Bipedalism is the use of two feet for standing and walking. Nearly all primates are capable of bipedalism, although most of the primates spend their time on all fours. Primates are known to move bipedally, but they also use bipedalism to stand up on their hind legs to reach food, look for predators, and for social display and communication.
