Drag the labels onto the equation to identify the inputs and outputs of cellular respiration.
marysya [2.9K]
<span>The inputs are also called reactants. In Cellular respiration, there are certain inputs in the form of glucose and oxygen. The outputs, generally known as the products, are water, carbon dioxide, and ATP molecules.

The general equation used to represent the inputs and outputs of cellular respiration is:

Glucose + Oxygen → Carbon Dioxide + Water + ATP + Heat + Energy

C₆H₁₂O₆ +6O₂ → 6CO₂ + 6H₂O + Energy (ATP+ Heat)</span>

In humans, XO individuals are females with Turner syndrome and XXY individuals are males with Klinefelter syndrome. Red green co
Nata [24]

Answer:

The correct answer is option E) "Nondisjunction at either meiosis I or meiosis II in the mother".

Explanation:

Nondisjunction is a phenomena at which chromosomes are not properly separated during anaphase. This can either happen at meiosis I or meiosis II during oogenesis. Nondisjunction would explain the XO chromosomic condition of the daughter with Turner syndrome as well as the X-linked recessive allele of the red green color blindness. Nondisjunction happened in the mother because the father could not inherited an X-linked condition.

Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
yaroslaw [1]

Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.

Explanation:

Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.

When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.

For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
