Which biome would contain the most trees?

If ethyl alcohol contains almost as much energy as the original pyruvic acid, what can you infer about the efficiency of ferment

shusha [124]

Explanation:

Fermentation has a comparatively low efficiency as it produces the same amount of energy, whereas aerobic respiration produces up to 38 molecules of ATP .

Aerobic 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).

Within cells, aerobic respiration may not occur due to several factors:

- a lack of inorganic, final electron acceptors
-incomplete or lack of a complete electron transport system
-missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Net production of ATP in fermentation: 2 ATP
Net production of ATP in aerobic respiration ≈38 ATP

Further Explanation:

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

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 Citric acid or 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.

Which if the following accurately describes the life cycle of most gymnosperms

love history [14]

I found the exercise on the internet and bellow are the options:
"A. Seed cones contain ovules.
B. Germinated seeds are haploid.
C. A pollen tube is used to prevent the fertilization process.
<span>D. Pollen grains undergo meiosis to form egg cells."

The correct answer is D.
There are no seed cones, but pollen cones, where the ovules can be found. Germinated seeds are diploid, not haploid. The pollen tube role is to promote the fertilization process by leading the sperm to the egg, once the sperm in this type of plants do not have flagella and therefore no movement.
The correct answer is D because pollen grains are really the diploid germinative cells that </span><span>produce sperm cells.</span>

5. In your everyday life, you have probably noticed that certain instruments are ideal for certain situations. For example, you

MaRussiya [10]

Answer:

A light microscope, particularly when the cell has indeed been spattered to disclose information, would've been ideal when examining a small living organism.

Explanation:

A light microscope is a laboratory biology instrument or device that uses transparent sensors to illuminate and exacerbate and enlarge, very small objects. Individuals use lenses to center light on the test sample, thereby amplifying it to produce an image. The experiment is usually located near the respective.

It does this by producing a magnified image using a series of glass lenses, which first focuses a laser light on or through an object, then conveys objective lenses to expand the created image.

Some will require energy and a transporter protein in the membrane. Amino acids use this form of transport, called ____________

bearhunter [10]

Answer:

Active transport

Explanation:

The process of transport of substances that uses energy and carrier proteins of the membrane is called active transport. Amino acids can not cross the hydrophobic core of the membrane and therefore, are transported through carrier proteins. The carrier proteins transport the amino acids using energy and the process is called active transport.
