The activity of the pyruvate dehydrogenase complex is also controlled by phosphorylation. Pyruvate dehydrogenase kinase (PDH kinase) catalyzes the phosphorylation of a specific Ser residue on the E1 subunit of the enzyme, rendering it inactive. Pyruvate dehydrogenase phosphatase (PDH phosphatase) reverses the inhibition by catalyzing the removal of this phosphate group. The PDH kinase is highly regulated and its activity is influenced by various cellular metabolites. Indicate whether the following would activate or inhibit PDH kinase:
Inhibit or activate PDK?
NAD+ activate
NADH inhibit
coenzyme A activate
acetyl-CoA inhibit
ADP inhibit
Did I answer these correctly?
Answer:
Increase in [NAD+] inhibits Pyruvate dehydrogenase kinase (PDH kinase)
Increase in [NADH] activates Pyruvate dehydrogenase kinase (PDH kinase)
Coenzyme A inhibits Pyruvate dehydrogenase kinase (PDH kinase)
Acetyl-co A activates Pyruvate dehydrogenase kinase (PDH kinase)
ADP inhibits Pyruvate dehydrogenase kinase (PDH kinase)
Explanation:
Pyruvate dehydrogenase kinase, PDK is an enzyme which acts to inhibit the activity of the enzyme pyruvate dehydrogenase by phosphorylating it using ATP. It mechanism of action is by catalyzing the phosphorylation of a specific Ser residue on the E1 subunit of the pyruvate dehydrogenase complex, rendering it inactive. By inhibiting the activity of the pyruvate dehydrogenase complex, PDK will decrease the oxidation of pyruvate to acpcetyl-coA and CO₂ in the mitochondria and increase the conversion of pyruvate to lactate in the cytosol.
Since pyruvate dehydrogenase complex is activated by either an increase in the concentration of one or more of ADP, NAD+ or CoA-SH, its inhibitor pyruvate dehydrogenase kinase is inhibited by ADP, NAD+, CoA-SH and pyruvate. However, PDK is activated by increase in the concentration of ATP, NADH and acetyl-CoA.
Therefore, the correct answers are:
Increase in [NAD+] inhibits Pyruvate dehydrogenase kinase (PDH kinase)
Increase in [NADH] activates Pyruvate dehydrogenase kinase (PDH kinase)
Coenzyme A inhibits Pyruvate dehydrogenase kinase (PDH kinase)
Acetyl-co A activates Pyruvate dehydrogenase kinase (PDH kinase)
ADP inhibits Pyruvate dehydrogenase kinase (PDH kinase)

Heat energy is converted to mechanical energy that’s used for muscle movements.
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.

why can the plant grow new parts but we cannot?
Answer: because, humans can't/don't regenerate in the same way
Explanation:
Plants excel in regenerating new parts due to factors like meristematic tissues, totipotency, indeterminate growth, and unique genetic traits. These enable continuous cell division, organ regeneration, and lifelong growth, while human regenerative abilities are more limited and specialized.
Plants have the remarkable ability to grow new parts due to their unique characteristics and physiological processes. While humans and other animals also have the ability to regenerate certain tissues and organs. Here are a few reasons why plants can grow new parts more effectively:
Meristematic Tissues: Plants have specialized regions called meristems that contain undifferentiated cells capable of continuous division and differentiation. These meristematic tissues are found in areas such as the tips of roots and shoots, allowing for continuous growth and regeneration. In contrast, humans have limited areas of active cell division, such as the bone marrow and the skin's basal layer, which restricts our regenerative capacity.
Totipotency: Plant cells have a higher degree of totipotency, meaning they have the potential to differentiate into various cell types and give rise to a whole plant. This property allows plants to regenerate entire organs, such as roots, stems, leaves, and even whole plants from small tissue pieces. In humans, cell differentiation is more specialized and limited, making it challenging to regenerate complete organs.
Indeterminate Growth: Most plants exhibit indeterminate growth, meaning they can grow throughout their lifespan. This continuous growth allows plants to replace damaged or lost parts by generating new tissues and organs. In contrast, humans and animals typically have determinate growth, where growth ceases or significantly slows down after reaching a certain size or age.
Hence, plants grow, but humans can't grow.

If the amino acids glycine, alanine and valine were combined in one molecule, what would the molecule be called?
Answer:
A tripeptide
Explanation:
Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).

Answer:
The correct answer is -
1.1 A. herbivore - greenfly
b. producer - rose
1.2. 1 kJ/m2/year
1.3 rose plants will increase, ladybirds will decrease, blackbirds will decrease.
Explanation:
In this food chain,
Rose >>Greenfly >>Ladybird >>Blackbird
Rose plants are the producers as they generate their food and energy and does not depend on other organisms where as greenfly are the primary consumer or herbivore as they depend on the rose plant for their food and energy only, however, ladybird as secondary consumer and blackbird as tertiary consumer depend on greenfly and ladybird respectively.
If rose plants have 1000 kJ/m2 /year of energy and as it is known that only 10% moves to the next tropic level then blackbird would have:
rose = 1000
greenfly = 1000*10/100= 100 kJ
ladybird = 100*10/100 = 10kJ
blackbird = 10*10/100 = 1 kJ
If greenfly removes from here the rose plant will increase as these depends and eat rose plants and lady bird will decrease as these are the primary source of food for lady bird and if ladybird decrease blackbird also decrease.
