Three characteristics of enzymes​

Biology
2 answers:
natita [175]3 years ago
8 0

Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes are proteins, and therefore are folded chains of amino acids with a specific shape. This shape is determined by the sequence of amino acids held together by bonds, for example Hydrogen bonds. Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction).

Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit.  The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.

1)Enzyme is a protein. The main material of an enzyme is protein
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor.
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.

Why does Red transfer all its momentum to Green?
Archy [21]
<h2>Answer with Explanation </h2>

I have been as of late pondering, on the off chance that I take a sufficiently incredible vitality source (photon) and I have an ideal mirror precisely before it and expect a "producer" shot the light towards the mirror. As impeccable mirrors assimilate no vitality of ANY sort from photons, should this imply the ideal mirrors could never move because of exchange of force of the light? it depends on the mass of the mirror, obviously. Your ideal mirror would have a vast mass, in which case it could assimilate the force change, without engrossing any vitality. A reflection of limited mass will ingest some vitality in a crash that will change the vitality and along these lines the wavelength of the photon. There is no logical inconsistency here.

Does the net gain of atp in glycolysis differ when glycogen, rather than glucose, is the starting material? what is the change?.
salantis [7]

The energy is greater and producing a net gain of ATP in glycolysis of 3 ATP.

<h3>What is glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. binding energy of carbs is captured. Retention of ATP One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid)
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route. In fact, the events that make up glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, also in the absence of enzymes, and are catalyzed by metal.

Reactive oxygen species (ROS) are unstable, or reactive, compounds that result from the partial reduction of oxygen. ROS can cau
soldier1979 [14.2K]

Answer:

OH, H2O2 and O−2

Explanation:

Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.

aniked [119]

Answer:

B (active transport using ATP)

Explanation:

Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.

In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).

An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.
