Answer:

Please find the explanation to this question below

Explanation:

The ATP cycle is the series of reactions involving glycolysis, Krebs cycle and oxidative phosphorylation that produces/synthesizes ATP in living cells. These processes collectively is called CELLULAR RESPIRATION. Glycolysis produces 2ATP molecules, Krebs cycle produces 2ATP while the electron transport chain (oxidative phosphorylation) produces 34ATP molecules.

This cycle of ATP as explained above is an important frequent event in cells because all organisms need energy to carry out their metabolic activities. ATP is the energy-carrying molecule that stores and releases energy for use by the cells, hence, it needs to be produced on a frequent basis.

ATP can be likened to a charged battery ready to release its stored energy. The energy is stored in the phosphate bonds that makes up its structure. When ATP releases its energy, it becomes ADP (Adenosine diphosphate). However, ADP is a reactant in the ATP cycle, which is phosphorylated with an inorganic phosphate (Pi) and catalyzes by ATP synthase to form ATP.

47. This cladogram shows the evolutionary relationships among some mammals

Fed [463]

Complete question:

This cladogram shows the evolutionary relationships among some mammals based on homologous structures.

(You will find the cladogram in the attached files)

Which statement is supported by this cladogram?

A Hippopotamuses are more closely related to cows than to javelinas.

B Toothed whales are more closely related to mouse deer than to hippopotamuses.

C Javelinas and pigs are more closely related than baleen whales and toothed whales.

D Cows and mouse deer are more closely related than javelinas and pigs.

Answer:

A Hippopotamuses are more closely related to cows than to javelinas.

Explanation:

A cladogram is a branched diagram of characteristics shared by the organisms of a group, that represents the most probable evolutive history of the linage. Cladograms reflect the phylogenetic relationships among groups through phylogenetic trees.

In the phylogenetic tree, the taxonomic groups of interest are located in the extremes of the lines called branches. The ramification point, which is also called "node" or divergence point, represents the location of the most recent common ancestor.

The common ancestor position will determine how related are two species. If they have a recent common ancestor, they are closely related to each other. On the other hand, if the common ancestor is not recent and is located far away in the tree, then the two species will be less related to each other.

A Hippopotamuses are more closely related to cows than to javelinas. TRUE. Hippopotamuses share a common more recent ancestor with cows than with javelinas. This means that the hyppopotamus is more related to cows than to javelinas. The arrows in the cladogram (attached file) show the positions of the common ancestor shared by Hippopotamuses and Cows, and the common ancestor shared by Hippopotamuses and Javelinas.

B Toothed whales are more closely related to mouse deer than to hippopotamuses. FALSE. Tooth whales are more related to the hyppopotamus. Their common ancestor is more recent than the common ancestor between toothed whales and mouse deer. The arrows in the cladogram (attached file) show the positions of the common ancestors.

C Javelinas and pigs are more closely related than baleen whales and toothed whales. FALSE. They are equally related.

D Cows and mouse deer are more closely related than javelinas and pigs.

FALSE. They are equally related.

State the identities of the substrate , enzyme and product involves .

tester [92]

Enzymes are Biological Catalysts. They increase the rate of Metabolic reactions. Almost all Biological Reactions involve Enzymes. All enzymes are Globular Proteins with a specific Tertiary Shape. They are usually specific to only one reaction.The part of the Enzyme that acts a Catalyst is called the Active Site. The rest of the Enzyme is much larger and is involved in maintaining the specific shape of of the Enzyme.When a reaction involving an Enzyme occurs, a Substrate is turned into a Product. The Substrate can be one or more molecules. The Active Site of an Enzyme is Complementary to the Substrate it catalyses.

Help me, please with this :)

WARRIOR [948]

Answer:

Please find the answer to the blank spaces in each statement of the attached image in CAPS.

1. All energy comes from the SUN

2. Plants, algae and some bacteria capture energy by PHOTOSYNTHESIS in their CHLOROPLAST.

3. Plants, animals, fungi, protists, and most bacteria release energy by RESPIRATION in their MITOCHONDRIA.

Note:

- Photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02)

- Respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER

Explanation:

The image in this diagram is depicting how energy flows from the ultimate source, which is the SUN to other living organisms. Plants, algae and some bacteria have the ability to capture energy from the SUN using pigments in their CHLOROPLAST in a process called PHOTOSYNTHESIS, which they use to synthesize their food. The process of photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02) gas.

However, on the contrary, virtually all living organisms including: Plants, animals, fungi, protists, and most bacteria etc. release energy via an organelle called MITOCHONDRIA in a process called RESPIRATION. The process of respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER.
