the peptide bond  limits the possible orientations of the peptide backbone in a protein. it is a dehydration synthesis reaction.

A peptide bond in organic chemistry is a sort of covalent chemical bond called an amide that connects two alpha-amino acids in a row starting from C1 (carbon number one) of one and N2 (nitrogen number two) of another, along a peptide or protein chain. It can also be referred to as a "eupeptide bond" to differentiate it from a "isopeptide bond," which is an additional kind of amide bond that connects two amino acids. Condensation reaction occurs when two amino acids combine to create a dipeptide through a peptide link. Two amino acids condense in this manner when their non-side chain (C1) carboxylic acid moiety approaches their non-side chain (N2) amino moiety.

Option 2 is Correct. The various orientations of the peptide backbone of a protein are restricted by the peptide bond.

In organic chemistry, an amide chemical bond known as a peptide bond joins two alpha-amino acids in a row beginning with C1 (carbon number one) of one and N2 (nitrogen number two) of another, along a peptide or protein chain. To distinguish it from an extra type of amide bond that joins two amino acids, known as a "isopeptide bond," it can alternatively be referred to as a "eupeptide bond."

When two amino acids unite to form a dipeptide through a peptide link, condensation process takes place. When the non-side chain (C1) carboxylic moiety of two amino acids approaches the non-side chain (N2) amino moiety, they condense in this way.

True. Body planes are the cutting surfaces used to make cuts in the body or even a structure for anatomical as well as pathological research.

Body planes are fictitious geometric planes that are used to segment the body. They are frequently used to define the position or angular orientation of body structures in both animal and human anatomy. The Sagittal Plane (also known as the Lateral Plane) is a vertical plane that runs from front to back and divides the body into its right and left sides. The typical anatomical stance for a human is standing with their feet together again and pointing forward, without any long bones being crossed from the observer's point of view. (Sagittal, Coronal, Transverse) Three anatomical planes allow for the slicing of tissues and/or the taking of photographs.

Photorespiration is defined as the addition of oxygen to RuBP by rubisco to form a two-carbon product, which is then broken down by the cell to carbon dioxide and water.

The evolution of CO2 during photosynthesis is known as photorespiration. It occurs as a result of rubisco's ability to function as either a carboxylase (incorporating CO2) or an oxygenase (incorporating O2). Rubisco functions primarily as a carboxylase in the presence of relatively high CO2 levels.

Photorespiration is the process by which molecular oxygen (O2) is taken up by light and carbon dioxide (CO2) is released from organic compounds. The gas exchange is similar to respiration and works in the opposite direction of photosynthesis, where CO2 is fixed and O2 is released.

In photosynthesis, energy is carried by various small and large molecules from one part of plant body to other part.

A substance response filled by the energy of the sun, photosynthesis changes over carbon dioxide, water and daylight into glucose and oxygen. Autotrophs, life forms like plants that make their own food, use photosynthesis to fuel development, proliferation and fix of their cells. Photosynthesis happens in two phases: the light-reliant responses and the light autonomous responses.

Since plants can't utilize the energy from the sun straightforwardly to create glucose, daylight is changed over into synthetic energy through the development of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate hydrogen (NADPH). During the light-reliant responses of photosynthesis, ATP and NADPH are made; these are energy-conveying particles. The synthetic energy put away in ATP and NADPH is then utilized during the light-free phase of photosynthesis, which is otherwise called the Calvin cycle, to create starches.

the following statements about good experiments is TRUE

A good experiment should have at least two groups: one control group and one experimental group.

An experimental group is a group of subjects in an experiment that is exposed to a manipulation of an independent variable, also known as a treatment. The experimental group is used as a point of comparison to a control group, which is not exposed to the manipulation of the independent variable. The goal of the experimental group is to determine whether the manipulation of the independent variable has an effect on the dependent variable, which is the outcome being measured. The experimental group allows researchers to establish cause-and-effect relationships between the independent and dependent variables, as the manipulation of the independent variable can be linked to changes in the dependent variable. The experimental group is an essential aspect of experimental design in scientific research, as it allows researchers to test hypotheses, evaluate theories, and draw conclusions about the phenomenon being studied.

The correct heading to which the given phrase is closely related is Calvin cycle (light-independent reactions of photosynthesis).

According to the definition of photosynthesis, it is the process through which certain microorganisms and green plants produce food when exposed to sunlight. When the organic molecule is in the presence of carbon dioxide, water, and sunlight, glucose is produced. The process by which oxygen is produced as a byproduct is called photosynthesis. An example of an oxidation-reduction reaction is photosynthesis. Water passes through oxidation whereas carbon dioxide goes through reduction.

The Kreb's cycle, often known as the citric acid cycle, is a critical phase of cellular respiration. The breakdown of acetyl coenzyme A (decarboxylated pyruvate) takes place in the mitochondrial matrix.

The fixation of carbon dioxide into sugar molecules occurs during the Calvin cycle, also known as the light-independent processes of photosynthesis. ATP and NADH are created as a result of the process, which occurs in the thylakoid membrane. In the absence of sunshine, the procedure takes place.

The photosynthesis process involves the transformation of light energy into chemical energy. Within thylakoids, the activity takes place in the presence of oxygen.

Ions must flow across the membrane during chemiosmosis. An electrochemical gradient is created as a result. The synthesis of ATP is driven by this electrochemical gradient.

Prokaryotes and eukaryotes engage in glycolysis, which involves the breakdown of glucose to produce energy. It is a crucial phase of the respiration process. Pyruvate, the byproduct of glycolysis, is added to a number of cycles to provide energy.
