Neither whales nor pythons have hind legs, but both have internal remnants of legs and hip bones. Snakes and whales must have I.
alexandr402 [8]

Answer:

I. evolved from ancestors that walked

Explanation:

Whales and pythons have vestigial structures, which are structures (hind legs) which are no longer useful to them since they have evolved. The ancestors of the whale and python did use the hind legs but over generations the whale and snake have adapted to new environments and they no longer need them.

Which of these statements are accurate? Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group fr
Agata [3.3K]

Answer:

A. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. True

B. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. True  

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. True

Explanation:

A. Hexokinase suffers and conformational changes by binding glucose in a reaction that prevents ATP hydrolysis.

B. Hexokinase is an enzyme with two domains that function by binding to the substrate (i.e., glucose). The region linking both protein domains is responsible for the catalytic activity.

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. During the first stage of glycolysis, the hexokinase transfers one phosphorous group from magnesium-ATP (Mg-ATP) to one hexose molecule, such as fructose, mannose or glucose.

 

False statements:

- Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. False: In canonical kinases, conserved amino acids bind to divalent metal ions before the transference of the phosphate group to their substrates.

- Hexokinase is found in the mitochondrial membrane. False: Hexokinase is found in the cytosol.

- Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. False: Hexokinase catalyzes the transfer of the terminal phosphate ATP to form glucose 6-phosphate.

The photosynthetic pigment in plants that reflects green wavelengths and absorbs red and blue wavelengths is

Chlorophyll

Which metabolic process converts light energy into chemical energy?

photosynthesis

The potential energy within ATP molecules is stored in the ______.

bonds between the phosphates.

The most important result of photosynthesis is the __________.

conversions of light energy to chemical energy.

The Calvin cycle of photosynthesis CANNOT proceed __________.

without the products of the light reaction

The light reactions of photosynthesis take place on the ________ of the ___________.

thylakoid membranes, chloroplast

The part of the plant where most photosynthesis occurs is generally the ___________.

leaves

When split by the process of _______, electrons from molecules of ________replace electrons lost from chlorophyll in Photosystem II and then ________ is released.

photolysis, water, oxygen

The products of the Calvin cycle include what?

sugars

Which of the following statements about the overall reaction for photosynthesis is true?

Carbon dioxide contributes carbon and oxygen to sugar

In the carbon cycle of an ecosystem, inorganic carbon in the atmosphere is converted to organic compounds through _____.

photosynthesis

Where do fermentation and glycolysis take place?

in the cytoplasm of cells

Many scientists think that the rise in global temperatures is linked to increasing atmospheric levels of ____.

carbon dioxide

Photosynthesis and cellular respiration are related because _______.

The products of photosynthesis are the raw products for glucose metabolism and the products of glucose metabolism are the raw products for photosynthesis

What is glycolysis?

The breakdown of glucose to form two molecules of pyretic acid.

Respiration is the process of gas exchange (breathing in oxygen and out carbon dioxide); cellular respiration is the process of_______.

producing ATP via glycolysis, the Krebs cycle, and the ETC

How is the oxygen that heterotrophs such as fish and salamanders breath in used in cellular respiration?

Oxygen is the final electron acceptor of the ETC

In eukaryotic cells, glycolysis occurs in the ______ and the cellular respiration occurs in the _______.

cytoplasm, mitochondria

The difference in charge (H+ concentration) on the inside and the outside of mitochondrial membranes supplies the energy for _________.

the formation of ATP

Why does death result from any situation that prevents a person from breathing?

Oxygen is needed for cellular respiration, so lack of oxygen prevents ells from making sufficient ATP for essential cellular functions. Cells die as a result, eventually leading to the death of the individual.

Alcoholic fermentation releases ethyl alcohol (ethanol) and _______.

CO2 and ATP

The overall equation for cellular respiration is C6H12O6 ------> 6CO2 + 6H2O + ATP and heat. The oxygen atoms in the CO2 molecules in this equation are produced from ________ during reactions of the ___________.

C6H12O6, the Krebs cycle

At he bingeing of most recipes for bread, you are instructed to dissolve the yeast in a mixture of sugar and hot water, in some cases with a small amount of flour. Within a short time, this yeast mixture begins to bubble and foam, perhaps to the point of overflowing the container. What is happening? (Note that yeast is an unusual organism that produces ATP via fermentation when sucrose and oxygen are present, even though it could make more ATP via cellular respiration).

The bubbles are carbon dioxide that the yeast produce as they break down the glucose and produce ATP via fermentation.

Why should anyone care about the importance of ATP production?

The multicellular organism requires energy produced to carry out vital functions essential for survival, and understanding glycolysis and cellular respiration permits insight into how different organisms manage their energy needs in different environments.

The difference between aerobic and anaerobic respiration is that _____________.

Aerobic requires oxygen, anaerobic does not, and aerobic converts more energy

When you exercise strenuously, your muscle cells will switch to _________.

lactic acid fermentation

Cellular respiration releases most o the energy in this phase of the pathway.

ETC

What is the inner membrane of the mitochondria called?

cristae

Reactions that require energy to form more complex compounds are called _________ reactions.

anabolic

Some of the products of the Krebs cycle include ________.

ATP, NADH, CO2

Aerobic

reactions that require oxygen

Mitochondria

site of cellular respiration

ATP

energy carrier within the cell

Glucose

primary energy source for cells

Autotroph

organism that can make it's own food

Fermentation

process used by yeast and other microorganisms to harvest energy

Anaerobic

reactions that do not require oxygen to break down glucose

Catabolic

reactions that break down molecules to release energy

Heterotroph

organism that cannot make its own food
